Support disabling of policy on a given Virtual Machine Interface

[Ashok Singh]

This bug is to track changes required to support disabling of policy on Virtual Machine Interface.

When policy is disabled, features like SG, floating-IP, VN based policy and VRF assign rules configured on that interface will not be functional.

When policy is enabled, flows are created by the system. When DNS server is hosted on a VM, the number of DNS queries coming from different clients was huge resulting in too many flows. So providing an option to disable flows to improve performance for cases where flows are not really required.
