Merge "@Immutable GroupEntity"

@Immutable GroupEntity

Contrary to the earlier 3a5d1e58dadf17654064234bdeb08597b7a48fe5 which
made FlowEntity @Immutable about 3 months ago, this change has no
impacts in downstream project netvirt (because all of its GroupEntity
instantiations go through MDSALUtil, which is adjusted here as well).
