These are the changes in opserver to track redis connection status

UVEServer is enhanced to catch exceptions when redis failure happen, and remove redis connections
The connections are recreated when needed.

Also, when a redis connection goes up or down, we update the connection status in the analytics node UVE.

The "Redis" connection type is split between "Redis-UVE" and "Redis-Query"
