Add support for compression in http api
...
The need has been spotted in issue https://github.com/hashicorp/consul/issues/3687 .
Using "NYTimes/gziphandler", the http api responses can now be compressed if required.
The Go API requires compressed response if possible and handle the compressed response.
We here change only the http api (not the UI for instance).

[BUGFIX] When a node level check is removed, ensure all services of node are notified
...
Bugfix for https://github.com/hashicorp/consul/pull/3899
When a node level check is removed (example: maintenance),
some watchers on services might have to recompute their state.
If those nodes are performing blocking queries, they have to be notified.
While their state was updated when node-level state did change or was added
this was not the case when the check was removed. This fixes it.

See https://github.com/hashicorp/consul/issues/3937#issuecomment-370610509
for details.
It basically add a new option called `a_record_limit` and will not
return more than a_record_limit when performing A, AAAA or ANY DNS
requests.
The existing `udp_answer_limit` option is still working but should
be considered as deprecated since it works only with DNS clients
not supporting EDNS.

[Revert] Only update services if tags are different

This patch did give some better results, but break watches on
the services of a node.
It is possible to apply the same optimization for nodes than
to services (one index per instance), but it would complicate
further the patch.

Fixes #3891 : agent monitor no longer unresponsive before logs stream.
...
The root cause is actually that the agent's streaming HTTP API didn't flush until the first log line was found which commonly was pretty soon since the default level is INFO. In cases where there were no logs immediately due to level for instance, the client gets stuck in the HTTP code waiting on a response packet from the server before we enter the loop that checks the shutdown channel from the signal handler.
This fix flushes the initial status immediately on the streaming endpoint which lets the client code get into it's expected state where it's listening for shutdown or log lines.

Services Indexes modified per service instead of using a global Index
...
This patch improves the watches for services on large cluster:
each service has now its own index, such watches on a specific service
are not modified by changes in the global catalog.
It should improve a lot the performance of tools such as consul-template
or libraries performing watches on very large clusters with many
services/watches.

Makes server manager shift away from failed servers from Serf events.
...
Because this code was doing pointer equality checks, it would work for
the case of a failed attempted RPC because the objects are from the
manager itself:
https://github.com/hashicorp/consul/blob/v1.0.3/agent/consul/rpc.go#L283-L302
But the pointer check would always fail for events coming in from the
Serf path because the server object is newly-created:
https://github.com/hashicorp/consul/blob/v1.0.3/agent/router/serf_adapter.go#L14-L40
This means that we didn't proactively shift RPC traffic away from a
failed server, we'd have to wait for an RPC to fail, which exposes
the error to the calling client.
By switching over to a name check vs. a pointer check we get the correct
behavior. We added a DEBUG log as well to help observe this behavior during
integrated testing.
Related to #3863 since the fix here needed the same logic duplicated, owing
to the complicated atomic stuff.
/cc @dadgar for a heads up in case this also affects Nomad.
