Pg_rewind failure fix

Browse Source 
This commit fixes a small issue with Patroni where sometimes pg_rewind
would fail due to limitations in Postgres 9.5. To combat pg_rewind
failures, we can enable remove_data_directory_on_rewind_failure which
will cleanup the data directory on the pod and recreates it as a
replica so that the pod can restart from fresh, rather than churning in
an error state. This commit also sets
remove_data_directory_on_diverged_timelines to give Patroni a greater
ability to combat timeline divergence errors.
