Subject Review Request 62835: Use compatible Curator session and connection timeouts

Review request for Aurora, John Sirois and Bill Farner.

Repository: aurora


Curator will warn if used with a connection timeout that is lower than
the session timeout [1]. As it uses a default connection timeout of 15s
[2], this warning will be emitted using the Aurora default settings.

This patch remedies this issue in two ways:

* Making the Curator connection timeout configurable
* Bumping the session timeout to 15s. The current default of 4s is
  pretty small and could lead to unexpected failovers during long GC
  pauses. This is especially problematic as a failover in Aurora can
  be lengthy.
