dns: provide correct SOA and NS responses
...
This patch changes the behavior of the DNS server as follows:
* The SOA response contains the SOA record in the Answer section instead
of the Authority section. It also contains NS records in the Authority
and the corresponding A glue records in the Extra section.
In addition, CNAMEs are added to the Extra section to make the
MNAME of the SOA record resolvable.
AAAA glue records are not yet supported.
* The NS response returns up to three random servers from the
consul cluster in the Answer section and the glue A
records in the Extra section.
AAAA glue records are not yet supported.

* Removes the "consul" service from local state.
Since this service is added by the leader, it doesn't really make sense to
also keep it in local state (which requires special ACLs to configure), and
requires a bunch of special cases in the local state logic. This requires
fewer special cases and makes ACL bootstrapping cleaner.
* Makes coordinate update ACL log message a warning, similar to other AE warnings.

rpc: monkey patch fix for data races for localState
...
The tests that use the localState of the agent access the internal
variables and call methods which are not guarded by locks creating
data races in tests. While the use of internal variables is somewhat
easy to spot the fact that not all methods are thread-safe is a
surprise.
A proper fix requires the localState struct to be moved into its own
package so that tests in the agent can only access the external
interface.
However, the localState is currently dependent on the agent.Config
which would create a circular dependency. Therefore, the Config
struct needs to be moved first for this to happen.
This patch literally monkey patches the use of the lock around the
cases which have data races and marks them with a
// todo(fs): data race comment.

agent: fix DNS recursor tests ( #3190 )
...
The makeRecursor function was using an unreliable mechanism
to start a server with a random port. This patch changes this
so that the server starts on port 0 to let the kernel pick
a free port.
In addition, to similar functions for starting a test DNS
server were folded into one.

agent: fix 'consul leave' shutdown race ( #2880 )
...
When the agent is triggered to shutdown via an external 'consul leave'
command delivered via the HTTP API then the client expects to receive a
response when the agent is down. This creates a race on when to shutdown
the agent itself like the RPC server, the checks and the state and the
external endpoints like DNS and HTTP.
This patch splits the shutdown process into two parts:
* shutdown the agent
* shutdown the endpoints (http and dns)
They can be executed multiple times, concurrently and in any order but
should be executed first agent, then endpoints to provide consistent
behavior across all use cases. Both calls have to be executed for a
proper shutdown.
This could be partially hidden in a single function but would introduce
some magic that happens behind the scenes which one has to know of but
isn't obvious.

agent: fix 'consul leave' shutdown race ( #2880 )
...
When the agent is triggered to shutdown via an external 'consul leave'
command delivered via the HTTP API then the client expects to receive a
response when the agent is down. This creates a race on when to shutdown
the agent itself like the RPC server, the checks and the state and the
external endpoints like DNS and HTTP. Ideally, the external endpoints
should be shutdown before the internal state but if the goal is to
respond reliably that the agent is down then this is not possible.
This patch splits the agent shutdown into two parts implemented in a
single method to keep it simple and unambiguos for the caller. The first
stage shuts down the internal state, checks, RPC server, ...
synchronously and then triggers the shutdown of the external endpoints
asychronously. This way the caller is guaranteed that the internal state
services are down when Shutdown returns and there remains enough time to
send a response.
