BigSwitch Plugin: router interface immediately deleted from backend

[Kevin Benton]

Depending on the timing, a router interface may immediately be deleted from the backend after being created.

This is because the async creation thread cannot find the port to update its status after creating it on the backend. It assumes this is because it was already deleted so it deletes it from the backend even though the real cause is that it hasn't even been flushed to the db yet from the add_router_interface transaction.

    BigSwitch: Create router ports synchronously

    Since router ports are created as part of a
    long transaction with multiple REST calls, they
    need to be created sychronously. This is to prevent
    the async thread from deleting them from the backend
    if it can't find them in cases where they haven't been
    committed to the DB yet.
