Remove tables that store the mapping between neutron and Nuage VSD resources

[Sayaji Patil]

Nuage plugin stores a mapping of neutron and VSD id's for every neutron resource.
This bug is to remove the mapping to avoid storing redundant data and also avoid the
upgrade and out of sync issues.

    Changes to remove the use of mapping tables from Nuage plugin

    Nuage plugin maintains a mapping of Openstack and Nuage resources.
    With this change Nuage VSD can itself maintain this mapping, so the
    plugin doesn't have to store the information in the neutron DB.
    This eliminates potential out of sync and upgrade issues.
