This option specifies the driver to be used for the servicegroup service.

ServiceGroup API in dmapi enables checking status of a compute node. When a
compute worker running the dmapi-compute daemon starts, it calls the join API
to join the compute group. Services like dmapi scheduler can query the
ServiceGroup API to check if a node is alive. Internally, the ServiceGroup
client driver automatically updates the compute worker status. There are
multiple backend implementations for this service: Database ServiceGroup driver
and Memcache ServiceGroup driver.

Possible Values:

    * db : Database ServiceGroup driver
    * mc : Memcache ServiceGroup driver

Related Options:

    * service_down_time (maximum time since last check-in for up service)
