py-redis: updated to 3.5.3

3.5.3:
* Restore try/except clauses to __del__ methods. These will be removed
  in 4.0 when more explicit resource management if enforced.
* Update the master_address when Sentinels promote a new master.
* Update SentinelConnectionPool to not forcefully disconnect other in-use
  connections which can negatively affect threaded applications.
