Configure trove_conductor_workers in os_trove

Browse Source 
Configure trove_conductor_workers by calculating the default value.
Similar to other services worker threads, the default value for
trove_conductor_workers is half the number of vcpus on the machine.

Also added capping of worker threads for trove.
