[ONOS-5170] GroupStore: add purgeGroupEntries

The GroupStore exposes purgeGroupEntry, which purges
from the store by a specific device.

Add purgeGroupEntries, to purge entries from all devices
from the GroupStore, and expose purgeGroupEntries to allow
applications to purge all group entries from the GroupStore
without specifying a device.
