Roey Chen 81f9380765 NSXv BGP support
This change implement's a new BGP plugin which allows BGP support in Openstack,
using NSXv service edges (ESG).
When a BGP speaker is associated with an external network, service edges which
accommodates tenant routers that have their GW port on this network would be
configured to enable BGP/Dynamic-routing.
The specific BGP configuration (e.g - localAS, neighbours) for the edge is
retrieved from the BGP speaker object and its peers.

This change also adds an extension to the BGP peer object, this
extension allows the cloud operator to associate a BGP peer with a specific
service edge that will serve as GW edge for the network, multiple GW
edges are supported by enabling ECMP on tenant service edges.
