Gary Kotton 01d33ffa65 Integration with new neutron code
1. Use new enginefacade + l3_db breakage
Use reader and writer for db operations.
Partially-Implements blueprint: enginefacade-switch

2. Fix the callback pass for _prevent_l3_port_delete_callback
which was changed in commit Ia8ac4f510c003667cac95f76dea0e9ae55159878

3. QoS driver integration
Commit I5f747635be3fd66b70326d9f94c85a6736286bd2 removes the qos
notification driver.
Fixing the nsx-v and nsx-v3 to work only with the regular driver

4. _get_extra_routes_dict_by_router_id was removed by
Ia815d6c597730bd5cb49455e7409ca747a4cc22c

5. Floating IP association without subnet gateway IP
not supported by our plugins.
Added in commit If212c36d918ed57400a53f4b5fa1925b3d1fa6fd
