Merged requested to merge redis_proxy_cleanup into master
Some cleanup of !3220 (merged)
Redis connections: the client name was set twice
test_redis_connections: take into account that the tango db could be accessing Redis
Beacon connection: calling
SafeRedisProxy.closeon greenlet garbage collection makes no sense (it is a reusable proxy that is greenlet-safe). Only
FixedConnectionRedisDbProxy.closemakes sense (not greenlet-safe).
Beacon connection: simplify proxy and connection pools with
RedisProxyId(name, db, type). For each
RedisProxyIdwe will have one reusable
SafeRedisProxyand one Redis connection pool. We don't really need a different pool for a different name or type, but keep it for now.
