geneve gtpu vxlan vxlan-gpe: VRF-aware bypass node

Bypass node MUST NOT intercept a packet if destination IP doesn’t match
a local address.  However IP address interpretation depends on the VRF,
hence bypass node must take that into account.

This patch also factors-out common VTEP management and checking code.

Type: improvement
