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.

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.

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.

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`).

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).

If we get a coordinate then this test will fail, so we only check the

We take the interval and add the random stagger to it, so 2X is cutting it
