Oleg Bondarev 130655cdb9 DHCP notification optimization
DHCP notification is done after each create/update/delete for
network, subnet and port.
This notification currently has to retrieve network from DB almost
every time, which is a quite heavy DB request and hence affects
performance of port and subnet CRUD.

This patch suggests 2 optimizations:
- do not fetch network if not needed (only fetch when schedule needed)
- for port and subnet AFTER_CREATE event pass network dict from plugin

According to Rally tests these changes improve performance:
- port create ~20%
- port update ~20%
- subnet create ~15%
- port delete and subnet update/delete - not tested
