mesh: add options for HTTP incoming request normalization
Expose global mesh configuration to enforce inbound HTTP request
normalization on mesh traffic via Envoy xDS config.
mesh: enable inbound URL path normalization by default
mesh: add support for L7 header match contains and ignore_case
Enable partial string and case-insensitive matching in L7 intentions
header match rules.
ui: support L7 header match contains and ignore_case

test: add request normalization integration bats tests
Add both "positive" and "negative" test suites, showing normalization in
action as well as expected results when it is not enabled, for the same
set of test cases.
Also add some alternative service container test helpers for verifying
raw HTTP request paths, which is difficult to do with Fortio.
docs: update security and reference docs for L7 intentions bypass prevention
- Update security docs with best practices for service intentions
configuration
- Update configuration entry references for mesh and intentions to
reflect new values and add guidance on usage

* update golden files
* do not set engine type
When a large number of upstreams are configured on a single envoy
proxy, there was a chance that it would timeout when waiting for
ClusterLoadAssignments. While this doesn't always immediately cause
issues, consul-dataplane instances appear to consistently drop
endpoints from their configurations after an xDS connection is
re-established (the server dies, random disconnect, etc).
This commit adds an `xds_fetch_timeout_ms` config to service registrations
so that users can set the value higher for large instances that have
many upstreams. The timeout can be disabled by setting a value of `0`.
This configuration was introduced to reduce the risk of causing a
breaking change for users if there is ever a scenario where endpoints
would never be received. Rather than just always blocking indefinitely
or for a significantly longer period of time, this config will affect
only the service instance associated with it.

Fix issues with empty sources
* Validate that each permission on traffic permissions resources has at least one source.
* Don't construct RBAC policies when there aren't any principals. This resulted in Envoy rejecting xDS updates with a validation error.

Configure Envoy to use the same HTTP protocol version used by the
downstream caller when forwarding requests to a local application that
is configured with the protocol set to either `http2` or `grpc`.
This allows upstream applications that support both HTTP/1.1 and
HTTP/2 on a single port to receive requests using either protocol. This
is beneficial when the application primarily communicates using HTTP/2,
but also needs to support HTTP/1.1, such as to respond to Kubernetes
HTTP readiness/liveness probes.

* Fixes issues in setting status
* Update golden files for changes to xds generation to not use deprecated
methods
* Fixed default for validation of JWT for route
### Description
<!-- Please describe why you're making this change, in plain English.
-->
- Currently the jwt-auth filter doesn't take into account the service
identity when validating jwt-auth, it only takes into account the path
and jwt provider during validation. This causes issues when multiple
source intentions restrict access to an endpoint with different JWT
providers.
- To fix these issues, rather than use the JWT auth filter for
validation, we use it in metadata mode and allow it to forward the
successful validated JWT token payload to the RBAC filter which will
make the decisions.
This PR ensures requests with and without JWT tokens successfully go
through the jwt-authn filter. The filter however only forwards the data
for successful/valid tokens. On the RBAC filter level, we check the
payload for claims and token issuer + existing rbac rules.
### Testing & Reproduction steps
<!--
* In the case of bugs, describe how to replicate
* If any manual tests were done, document the steps and the conditions
to replicate
* Call out any important/ relevant unit tests, e2e tests or integration
tests you have added or are adding
-->
- This test covers a multi level jwt requirements (requirements at top
level and permissions level). It also assumes you have envoy running,
you have a redis and a sidecar proxy service registered, and have a way
to generate jwks with jwt. I mostly use:
https://www.scottbrady91.com/tools/jwt for this.
- first write your proxy defaults
```
Kind = "proxy-defaults"
name = "global"
config {
protocol = "http"
}
```
- Create two providers
```
Kind = "jwt-provider"
Name = "auth0"
Issuer = "https://ronald.local"
JSONWebKeySet = {
Local = {
JWKS = "eyJrZXlzIjog....."
}
}
```
```
Kind = "jwt-provider"
Name = "okta"
Issuer = "https://ronald.local"
JSONWebKeySet = {
Local = {
JWKS = "eyJrZXlzIjogW3...."
}
}
```
- add a service intention
```
Kind = "service-intentions"
Name = "redis"
JWT = {
Providers = [
{
Name = "okta"
},
]
}
Sources = [
{
Name = "*"
Permissions = [{
Action = "allow"
HTTP = {
PathPrefix = "/workspace"
}
JWT = {
Providers = [
{
Name = "okta"
VerifyClaims = [
{
Path = ["aud"]
Value = "my_client_app"
},
{
Path = ["sub"]
Value = "5be86359073c434bad2da3932222dabe"
}
]
},
]
}
},
{
Action = "allow"
HTTP = {
PathPrefix = "/"
}
JWT = {
Providers = [
{
Name = "auth0"
},
]
}
}]
}
]
```
- generate 3 jwt tokens: 1 from auth0 jwks, 1 from okta jwks with
different claims than `/workspace` expects and 1 with correct claims
- connect to your envoy (change service and address as needed) to view
logs and potential errors. You can add: `-- --log-level debug` to see
what data is being forwarded
```
consul connect envoy -sidecar-for redis1 -grpc-addr 127.0.0.1:8502
```
- Make the following requests:
```
curl -s -H "Authorization: Bearer $Auth0_TOKEN" --insecure --cert leaf.cert --key leaf.key --cacert connect-ca.pem https://localhost:20000/workspace -v
RBAC filter denied
curl -s -H "Authorization: Bearer $Okta_TOKEN_with_wrong_claims" --insecure --cert leaf.cert --key leaf.key --cacert connect-ca.pem https://localhost:20000/workspace -v
RBAC filter denied
curl -s -H "Authorization: Bearer $Okta_TOKEN_with_correct_claims" --insecure --cert leaf.cert --key leaf.key --cacert connect-ca.pem https://localhost:20000/workspace -v
Successful request
```
### TODO
* [x] Update test coverage
* [ ] update integration tests (follow-up PR)
* [x] appropriate backport labels added
