Rodolfo Alonso Hernandez 5250598c80 Improve scheduling L3/DHCP agents, missing lower binding indexes 
This patch is covering an edge case that could happen when the number
of DHCP agents ("dhcp_agents_per_network") or L3 agents
("max_l3_agents_per_router") has been reduced and there are more agents
assigned than the current number. If the user removes any agent
assignation from a L3 router or a DHCP agent, it is possible to remove
first the lower binding assigned registers.

Now the method ``get_vacant_binding_index`` calculates the number of
agents bound and the number required. If a new one is needed, the
method returns first the lower binding indexes not used.

Closes-Bug: #2006496

README 

This directory is designed to contain all SQLAlchemy models shipped with core
Neutron.

* The expected directory structure is flat, except for the ML2 plugins. All ML2
  plugin models should fall under the plugins subdirectory (i.e. plugins/ml2/gre_allocation).
* Module names should use singular forms for nouns (port.py, not ports.py).
