James Phillips fcaa889116 Bumps default Raft protocol to version 3. (#3477)
* Changes default Raft protocol to 3.

* Changes numPeers() to report only voters.

This should have been there before, but it's more obvious that this
is incorrect now that we default the Raft protocol to 3, which puts
new servers in a read-only state while Autopilot waits for them to
become healthy.

* Fixes TestLeader_RollRaftServer.

* Fixes TestOperator_RaftRemovePeerByAddress.

* Fixes TestServer_*.

Relaxed the check for a given number of voter peers and instead do
a thorough check that all servers see each other in their Raft
configurations.

* Fixes TestACL_*.

These now just check for Raft replication to be set up, and don't
care about the number of voter peers.

* Fixes TestOperator_Raft_ListPeers.

* Fixes TestAutopilot_CleanupDeadServerPeriodic.

* Fixes TestCatalog_ListNodes_ConsistentRead_Fail.

* Fixes TestLeader_ChangeServerID and adjusts the conn pool to throw away
sockets when it sees io.EOF.

* Changes version to 1.0.0 in the options doc.

* Makes metrics test more deterministic with autopilot metrics possible.
