2.8.0.rc0

This release builds on the 2.7.1 release by improving connection- and authentication-related diagnostics as well as streamlining handshake and authentication code.

The following notable tickets have been closed:

• RUBY-1728 Indicate which auth mechanism was used when auth fails
• RUBY-1743 Warn on handshake and auth failures
• RUBY-1744 When handshake/auth fails, indicate which server authentication was attempted against and whether ssl was used
• RUBY-1647 Reset connection pool on non-timeout network errors
• RUBY-1650 Rewrite connection handshake flow to not recurse
• RUBY-1717 Disconnecting connection pool should not reconnect connections
• RUBY-1441 Driver connects to cluster when closing stale sockets

We expect to release 2.8.0 final in about two weeks.
