GBP plugin

Group Base Policy (GBP) defines:
 - endpoints: typically a VM or container that is connected to the
              virtual switch/router (i.e. to VPP)
 - endpoint-group: (EPG) a collection of endpoints
 - policy: rules determining which traffic can pass between EPGs a.k.a
            a 'contract'

Here, policy is implemented via an ACL.
EPG classification for transit packets is determined by:
 - source EPG: from the packet's input interface
 - destination EPG: from the packet's destination IP address.
