agent: add allowStale option for HTTP API ( #3142 )

This patch adds an "allowStale" option to the HTTP API
configuration which allows stale reads to provide linear
read scalability.

This patch adds an "http_config" object to the config file

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: make the RPC endpoint overwrite mechanism more transparent
...
This patch hides the RPC handler overwrite mechanism from the
rest of the code so that it works in all cases and that there
is no cooperation required from the tested code, i.e. we can
drop a.getEndpoint().

Merge pull request #3154 from hashicorp/issue_2644_redux
...
Fix stale reads on server startup. Consistent reads will now wait for up to config.RPCHoldTimeout for the server to get past its raft log, before returning an error. Servers that are starting up will eventually catch up.
This fixes issue #2644

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.
