Fix quota class set APIs

v2.1 API which does not return the 'server_groups' and
'server_group_members' quotas in GET & PUT os-quota-class-sets
API response. v2 API used to return those keys in API response.

Also filter out the network related quotas from os-quota-class-sets
APIs

Fixing this with microversion.
