Title:
  unnecessary L3 rpcs

Status in networking-midonet:
  In Progress
Status in neutron:
  Won't Fix

Bug description:
  networking-midonet plugin currently issues RPCs for L3-agent unnecessarily.
  they are unnecessary as the plugin doesn't use neutron L3-agent at all.
  many (not all) of these RPCs are a consequence of using L3_NAT_db_mixin as a base class.  the plugin should use L3_NAT_dbonly_mixin instead.

  in order to do that, a few RPC assumptions in neutron needs to be fixed.
  namely,
  - ML2 uses disassociate_floatingips(do_notify), which is only available in L3_NAT_db_mixin 
  - a few l3 tests unnecessarily assume L3_NAT_db_mixin
