[MIE-1492] Too many Redis Connections

## Activity Streams creates too many Redis Connections.

Redis service dissconnects clients those who stand for 5 minutes in idle state. Then once the client detect that connection is gon, it tries to recconect and creates a new connection.

#### Changelog

- A new module redisWrapper was added in order to create a section where we could overwrite functionality from redis adpater.

- For each 4 minutes on idle state, the client will send a command queue (for instance "select(1)") what resets the idle timmer at redis service.
Is this done being implemented? It looks like if the Redis client disconnects and then reconnects, then cacheConnected will be false and we will not be able to write to the cache at all. You should either clear the cache and reconnect or just allow writes to go through; we do not think we should block all future writes.
