ToR Agent Performance - monitor request

Issue:
------
During initial response for monitor request, we end up
generating too many partial update for Physical port
entries causing lots of unneccessary processing on half
baked data. resulting in bad performance.

Fix:
----
Delay Creation of Physical Port entries, to be done
after processing of initial response to monitor request
is complete. This avoids processing triggers for partial
updates on physical port entries. Once we unable physical
port creation it will create physical port and stale
entries for vlan port bindings with completed information.
