Connect CA Primary Provider refactor (#16749)
* Rename Intermediate cert references to LeafSigningCert

Within the Consul CA subsystem, the term "Intermediate"
is confusing because the meaning changes depending on
provider and datacenter (primary vs secondary). For
example, when using the Consul CA the "ActiveIntermediate"
may return the root certificate in a primary datacenter.

At a high level, we are interested in knowing which
CA is responsible for signing leaf certs, regardless of
its position in a certificate chain. This rename makes
the intent clearer.

* Move provider state check earlier

* Remove calls to GenerateLeafSigningCert

GenerateLeafSigningCert (formerly known
as GenerateIntermediate) is vestigial in
non-Vault providers, as it simply returns
the root certificate in primary
datacenters.

By folding Vault's intermediate cert logic
into `GenerateRoot` we can encapsulate
the intermediate cert handling within
`newCARoot`.

* Move GenerateLeafSigningCert out of PrimaryProvidder

Now that the Vault Provider calls
GenerateLeafSigningCert within
GenerateRoot, we can remove the method
from all other providers that never
used it in a meaningful way.

* Add test for IntermediatePEM

* Rename GenerateRoot to GenerateCAChain

"Root" was being overloaded in the Consul CA
context, as different providers and configs
resulted in a single root certificate or
a chain originating from an external trusted
CA. Since the Vault provider also generates
intermediates, it seems more accurate to
call this a CAChain.

support vault auth config for alicloud ca provider
Add support for using existing vault auto-auth configurations as the
provider configuration when using Vault's CA provider with AliCloud.

AliCloud requires 2 extra fields to enable it to use STS (it's preferred
auth setup). Our vault-plugin-auth-alicloud package contained a method
to help generate them as they require you to make an http call to
a faked endpoint proxy to get them (url and headers base64 encoded).

xds: don't attempt to load-balance sessions for local proxies (#15789)
Previously, we'd begin a session with the xDS concurrency limiter
regardless of whether the proxy was registered in the catalog or in
the server's local agent state.

This caused problems for users who run `consul connect envoy` directly
against a server rather than a client agent, as the server's locally
registered proxies wouldn't be included in the limiter's capacity.

Now, the `ConfigSource` is responsible for beginning the session and we
only do so for services in the catalog.

connect: use -dev-no-store-token for test vaults to reduce source of flakes (#15691)
It turns out that by default the dev mode vault server will attempt to interact with the
filesystem to store the provided root token. If multiple vault instances are running
they'll all awkwardly share the filesystem and if timing results in one server stopping
while another one is starting then the starting one will error with:

    Error initializing Dev mode: rename /home/circleci/.vault-token.tmp /home/circleci/.vault-token: no such file or directory

This change uses `-dev-no-store-token` to bypass that source of flakes. Also the
stdout/stderr from the vault process is included if the test fails.

The introduction of more `t.Parallel` use in https://github.com/hashicorp/consul/pull/15669
increased the likelihood of this failure, but any of the tests with multiple vaults in use
(or running multiple package tests in parallel that all use vault) were eventually going
to flake on this.

connect: ensure all vault connect CA tests use limited privilege tokens (#15669)
All of the current integration tests where Vault is the Connect CA now use non-root tokens for the test. This helps us detect privilege changes in the vault model so we can keep our guides up to date.

One larger change was that the RenewIntermediate function got refactored slightly so it could be used from a test, rather than the large duplicated function we were testing in a test which seemed error prone.

Detect Vault 1.11+ import, update default issuer (#15253)
Consul used to rely on implicit issuer selection when calling Vault endpoints to issue new CSRs. Vault 1.11+ changed that behavior, which caused Consul to check the wrong (previous) issuer when renewing its Intermediate CA. This patch allows Consul to explicitly set a default issuer when it detects that the response from Vault is 1.11+.

freddygv fac3ddc857 Use internal server certificate for peering TLS
A previous commit introduced an internally-managed server certificate
to use for peering-related purposes.

Now the peering token has been updated to match that behavior:
- The server name matches the structure of the server cert
- The CA PEMs correspond to the Connect CA

Note that if Conect is disabled, and by extension the Connect CA, we
fall back to the previous behavior of returning the manually configured
certs and local server SNI.

Several tests were updated to use the gRPC TLS port since they enable
Connect by default. This means that the peering token will embed the
Connect CA, and the dialer will expect a TLS listener.

Add SpiffeID for Consul server agents (#14485)
Co-authored-by: Eric Haberkorn <erichaberkorn@gmail.com>

By adding a SpiffeID for server agents, servers can now request a leaf
certificate from the Connect CA.

This new Spiffe ID has a key property: servers are identified by their
datacenter name and trust domain. All servers that share these
attributes will share a ServerURI.

The aim is to use these certificates to verify the server name of ANY
server in a Consul datacenter.

Update RBAC to handle imported services (#13404)
When converting from Consul intentions to xds RBAC rules, services imported from other peers must encode additional data like partition (from the remote cluster) and trust domain.

This PR updates the PeeringTrustBundle to hold the sending side's local partition as ExportedPartition. It also updates RBAC code to encode SpiffeIDs of imported services with the ExportedPartition and TrustDomain.

Configure upstream TLS context with peer root certs (#13321)
For mTLS to work between two proxies in peered clusters with different root CAs,
proxies need to configure their outbound listener to use different root certificates
for validation.

Up until peering was introduced proxies would only ever use one set of root certificates
to validate all mesh traffic, both inbound and outbound. Now an upstream proxy
may have a leaf certificate signed by a CA that's different from the dialing proxy's.

This PR makes changes to proxycfg and xds so that the upstream TLS validation
uses different root certificates depending on which cluster is being dialed.

peering: replicate expected SNI, SPIFFE, and service protocol to peers (#13218)
The importing peer will need to know what SNI and SPIFFE name
corresponds to each exported service. Additionally it will need to know
at a high level the protocol in use (L4/L7) to generate the appropriate
connection pool and local metrics.

For replicated connect synthetic entities we edit the `Connect{}` part
of a `NodeService` to have a new section:

    {
      "PeerMeta": {
        "SNI": [
          "web.default.default.owt.external.183150d5-1033-3672-c426-c29205a576b8.consul"
        ],
        "SpiffeID": [
          "spiffe://183150d5-1033-3672-c426-c29205a576b8.consul/ns/default/dc/dc1/svc/web"
        ],
        "Protocol": "tcp"
      }
    }

This data is then replicated and saved as-is at the importing side. Both
SNI and SpiffeID are slices for now until I can be sure we don't need
them for how mesh gateways will ultimately work.

Support vault namespaces in connect CA (#12904)
* Support vault namespaces in connect CA

Follow on to some missed items from #12655

From an internal ticket "Support standard "Vault namespace in the
path" semantics for Connect Vault CA Provider"

Vault allows the namespace to be specified as a prefix in the path of
a PKI definition, but our usage of the Vault API includes calls that
don't support a namespaced key. In particular the sys.* family of
calls simply appends the key, instead of prefixing the namespace in
front of the path.

Unfortunately it is difficult to reliably parse a path with a
namespace; only vault knows what namespaces are present, and the '/'
separator can be inside a key name, as well as separating path
elements. This is in use in the wild; for example
'dc1/intermediate-key' is a relatively common naming schema.

Instead we add two new fields: RootPKINamespace and
IntermediatePKINamespace, which are the absolute namespace paths
'prefixed' in front of the respective PKI Paths.

Avoid using sys/mounts to enable namespaces (#12655)
* Avoid doing list of /sys/mounts

From an internal ticket "Support standard "Vault namespace in the path" semantics for Connect Vault CA Provider"

Vault allows the namespace to be specified as a prefix in the path of
a PKI definition, but this doesn't currently work for
```IntermediatePKIPath``` specifications, because we attempt to list
all of the paths to check if ours is already defined. This doesn't
really work in a namespaced world.

This changes the IntermediatePKIPath code to follow the same pattern
as the root key, where we directly get the key rather than listing.

This code is difficult to write automated tests for because it relies
on features of Vault Enterprise, which isn't currently part of our
test framework, so it was tested manually.

Daniel Nephin 1f00ede559 ca: require that tests that use Vault are named correctly
Previously we were using two different criteria to decide where to run a
test.  The main `go-test` job would skip Vault tests based on the
presence of the `vault` binary, but the `test-connect-ca-providers` job
would run tests based on the name.

This led to a scenario where a test may never run in CI.

To fix this problem I added a name check to the function we use to skip
the test. This should ensure that any test that requires vault is named
correctly to be run as part of the `test-connect-ca-providers` job.

At the same time I relaxed the regex we use. I verified this runs the
same tests using `go test --list Vault`.  I made this change because a
bunch of tests in `agent/connect/ca` used `Vault` in the name, without
the underscores. Instead of changing a bunch of test names, this seemed
easier.

With this approach, the worst case is that we run a few extra tests in
the `test-connect-ca-providers` job, which doesn't seem like a problem.
