Provide an option to enable/disable serve UVE queries from the aggregated
UVE db. In a scale setup, HA event (alarm-gen down), alarm-gen may take a
long time to aggregate the UVEs depending on the number of UVEs, number
of partitions it owns, etc., So, enabling this option would reduce the
down time in case of HA events (collector down - time taken for generators
to connect to the new collector and resync the UVEs, alarm-gen down - no
impact on UVE queries, only the alarms would be reevaluated)
