NSX: sync do not pass around model object

[Aaron Rosen]

The NSX sync backend previously passed around a sqlalchemy model object
around which was nice because we did not need to query the database an
additional time to update the status of an object. Unfortinately, this
was add done within a db transaction which included a call to NSX which
could cause deadlock this needed to be removed.

    The NSX sync backend previously passed around a sqlalchemy model object

    additional time to update the status of an object.

    Unfortunately, this was add done within a db transaction which included a
    call to NSX which could cause deadlock this needed to be removed. Now a
    dict is passed around instead and proper transaction handling
    is used when updating objects.
