Sean Chittenden d4ca349e21 Refactor out the management of Consul servers 
Move the management of c.consulServers (fka c.consuls) into consul/server_manager.go.

This commit brings in a background task that proactively manages the server list and:

*) reshuffles the list
*) manages the timer out of the RPC() path
*) uses atomics to detect a server has failed

This is a WIP, more work in testing needs to be completed.

Sean Chittenden 7b308d8d7e Add a flag to denote that a server is disabled 
A server is not normally disabled, but in the event of an RPC error, we want to mark a server as down to allow for fast failover to a different server.  This value must be an int in order to support atomic operations.

Additionally, this is the preliminary work required to bring up a server in a disabled state.  RPC health checks in the future could mark the server as alive, thereby creating an organic "slow start" feature for Consul.

Sean Chittenden 6af781d9d5 Rename `lastServer` to `preferredServer` 
Expanding the domain of lastServer beyond RPC() changes the meaning of this variable.  Rename accordingly to match the intent coming in a subsequent commit: a background thread will be in charge of rotating preferredServer.

Sean Chittenden fb0bfcc3cf Introduce GOTEST_FLAGS to conditionally add -v to go test 
Trivial change that makes it possible for developers to set an environment variable and change the output of `go test` to be detailed (i.e. `GOTEST_FLAGS=-v`).

Sean Chittenden f6ffbf4e96 Warn if serf events have queued up past 80% of the limit 
It is theoretically possible that the number of queued serf events can back up.  If this happens, emit a warning message if there are more than 200 events in queue.

Most notably, this can happen if `c.consulServerLock` is held for an "extended period of time".  The probability of anyone ever seeing this log message is hopefully low to nonexistent, but if it happens, the warning message indicating a large number of serf events fired while a lock was held is likely to be helpful (vs serf mysteriously blocking when attempting to add an event to a channel).

James Phillips 8a9ad3811b Gets rid of flaky sort check. 
If we get a coordinate then this test will fail, so we only check the
first item in the list, which is deterministic.

James Phillips fffa8d5061 Increases timeouts for coordinate tests. 
We take the interval and add the random stagger to it, so 2X is cutting it
too close and the unit tests are often flaky.

Miquel Sabaté Solà 4567963d8e command: deprecated the -dc flag in the agent CLI 
The `-dc` flag from the agent CLI command has been deprecated in favor of
`-datacenter`. This is done this way because:

- Other CLI commands used `-datacenter`. See: event, exec and watch.
- The agent configuration file uses `datacenter`.
