Daniel Nephin 0dfb7da610 grpc: fix a data race by using a static resolver
We have seen test flakes caused by 'concurrent map read and map write', and the race detector
reports the problem as well (prevent us from running some tests with -race).

The root of the problem is the grpc expects resolvers to be registered at init time
before any requests are made, but we were using a separate resolver for each test.

This commit introduces a resolver registry. The registry is registered as the single
resolver for the consul scheme. Each test uses the Authority section of the target
(instead of the scheme) to identify the resolver that should be used for the test.
The scheme is used for lookup, which is why it can no longer be used as the unique
key.

This allows us to use a lock around the map of resolvers, preventing the data race.

Daniel Nephin 70fea7a77e agent/grpc: fix a flaky test by performing more retries
Instead of using retry.Run, which appears to have problems in some cases where it does not
emit an error message, use a for loop.

Increase the number of attempts and remove any sleep, since this operation is not that expensive to do
in a tight loop

Daniel Nephin e640d47319 agent/grpc/resolver: namespace the server ID with the DC name
So that if two datacenters end up with overlapping serverIDs we don't send requests to the wrong server

Daniel Nephin ff3610850e agent/grpc: use router.Manager to handle the rebalance
The router.Manager is already rebalancing servers for other connection pools, so it can call into our resolver to do the same.
This change allows us to remove the serf dependency from resolverBuilder, and remove Datacenter from the config.

Also revert the change to refreshServerRebalanceTimer
