Revert "Cisco DFA ML2 Mechanism Driver"

This reverts commit 3680fd61c9a1cceaa011b4d0d37d235abf490c50.

The reverted patch incorrectly ties with Keystone and should have never been
approved since the approved version only partially addressed review concerns.

This revert also ensure migration timeline integrity.
