Public bug reported:

get_snat_port_for_internal_port retrieves the internal snat port created for each router interface added to a DVR router.
But this function is called twice in the L3 agent code.

for every interface add or delete to the router,  it is called by the
'dvr_local_router.py' and again it is called by the
'dvr_edge_router.py'.

This can be reduced to a single call to improve the controll plane
performance.
