Update sentinel support to allow multiple sentinel hosts

Browse Source 
Multiple sentinel hosts are now allowed by listing the additional
hosts as multiple 'sentinel_fallback' parameters. These are combined
with the first sentinel host to create a list that is provided to
Sentinel class constructor.

This provides safety in the case when the first (or any other) sentinel
host goes down.

Tests are run twice: once with fallbacks, once without.
