GA release v2.0.2

Changes since last release: v2.0.1...v2.0.2

There's been quite a few changes. Notable:

• added -c clusters-alias command
• Add orchestrator version and git commit to startup message
• Docker file changes & documentation
• after graceful takeover, old master is point below promoted master (but replication is not started and most like there won't even be replication credentials on the host)
• change to identity of successor host on intermediate master failover. To be continued & iterated.
• A TON of performance/scale fixes and changes via @sjmudd (thank you!):
  • added queue metrics
  • consolidated messages where number of involved servers is huge
  • bulk operations (multi-read vs. instance-by-instance read)
  • much more
• Web:
  • anonymizing user identity in anonymized mode
  • much cleanup

There's a mass of new commands to handle syncing of relay logs (MHA-style). This is still incomplete and its future is uncertain at this point. To be followed up.
