Fix a bug that wrongly trims domains when there is an overlap with DC 1.16.x (#18164)
Fix a bug that wrongly trims domains when there is an overlap with DC name (#17160)

* Fix a bug that wrongly trims domains when there is an overlap with DC name

Before this change, when DC name and domain/alt-domain overlap, the domain name incorrectly trimmed from the query.

Example:

Given: datacenter = dc-test, alt-domain = test.consul.
Querying for "test-node.node.dc-test.consul" will faile, because the
code was trimming "test.consul" instead of just ".consul"

This change, fixes the issue by adding dot (.) before trimming

* trimDomain: ensure domain trimmed without modyfing original domains

* update changelog

Parse peer name for virtual IP DNS queries (#13602)
This commit updates the DNS query locality parsing so that the virtual
IP for an imported service can be queried.

Note that:
- Support for parsing a peer in other service discovery queries was not
  added.
- Querying another datacenter for a virtual IP is not supported. This
  was technically allowed in 1.11 but is being rolled back for 1.13
  because it is not a use-case we intended to support. Virtual IPs in
  different datacenters are going to collide because they are allocated
  sequentially.

Add DNS recursor strategy option (#10611)
This change adds a new `dns_config.recursor_strategy` option which
controls how Consul queries DNS resolvers listed in the `recursors`
config option. The supported options are `sequential` (default), and
`random`.

Closes #8807

Daniel Nephin 204bf2b345 dns: correct rcode for qtype not supported
A previous commit started using QueryRefuced, but that is not correct. QueryRefuced refers to
the OpCode, not the query type.

Instead use errNoAnswer because we have no records for that query type.

Daniel Nephin d5cc206e39 streaming: move ServiceTag and NodeMetaFiltering to the cache-entry
So that all the client side filtering is in the same place. Previously
only the bexpr filter was in the cache-entry.

Also makes a small change to the filtering so that instead of rebuilding
slices of items, the filtering can return a bool to determine if the
event payload is saved or not.

Daniel Nephin b9e60c0775 testing: skip slow tests with -short
Add a skip condition to all tests slower than 100ms.

This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.
See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests

With this change:

```
$ time go test -count=1 -short ./agent
ok      github.com/hashicorp/consul/agent       0.743s

real    0m4.791s

$ time go test -count=1 -short ./agent/consul

Daniel Nephin 27b36bfc4e config: move NodeName validation to config validation
Previsouly it was done in Agent.Start, which is much later then it needs to be.

The new 'dns' package was required, because otherwise there would be an
import cycle. In the future we should move more of the dns server into
the dns package.

Daniel Nephin 2b920ad199 testing: fix flaky test TestDNS_NonExistentDC_RPC

The failure was: 'TestAgent.dns: rpc error: error=No known Consul servers'.

Waiting for the agent seems to fix it.

Chris Piraino b3db907bdf Update gateway-services-nodes API endpoint to allow multiple addresses
Previously, we were only returning a single ListenerPort for a single
service. However, we actually allow a single service to be serviced over
multiple ports, as well as allow users to define what hostnames they
expect their services to be contacted over. When no hosts are defined,
we return the default ingress domain for any configured DNS domain.

To show this in the UI, we modify the gateway-services-nodes API to
return a GatewayConfig.Addresses field, which is a list of addresses
over which the specific service can be contacted.

Returns DNS Error NSDOMAIN when DC does not exists (#8103)
This will allow to increase cache value when DC is not valid (aka
return SOA to avoid too many consecutive requests) and will
distinguish DC being temporarily not available from DC not existing.

Implement Client Agent Auto Config
There are a couple of things in here.

First, just like auto encrypt, any Cluster.AutoConfig RPC will implicitly use the less secure RPC mechanism.

This drastically modifies how the Consul Agent starts up and moves most of the responsibilities (other than signal handling) from the cli command and into the Agent.

Replace goe/verify.Values with testify/require.Equal (#7993)
* testing: replace most goe/verify.Values with require.Equal

One difference between these two comparisons is that go/verify considers
nil slices/maps to be equal to empty slices/maps, where as testify/require
does not, and does not appear to provide any way to enable that behaviour.

Because of this difference some expected values were changed from empty
slices to nil slices, and some calls to verify.Values were left.

* Remove github.com/pascaldekloe/goe/verify

Reduce the number of assertion packages we use from 2 to 1

Require individual services in ingress entry to match protocols (#7774)
