Missing plugin unit test coverage for allowed_address_pairs

[Salvatore Orlando]

Some plugins, at least openvswitch and ml2, are not inheriting the test case for allowed address pairs.

This means that the bits related to address pairs use cases in these plugins are currently not covered by unit tests.

    Openvswitch update_port should return updated port info

    Found when I enabled test_extension_allowedaddress_pairs, where
    test_create_port_removed_allowed_address_pairs would fail due to the
    returned port still containing the original addresspair. The cause is
    ovs simply not updating the port info being returned.

    This patch additionally enables test_extension_allowedaddress_pairs for
    openvswitch.

    Moved checks and updating into method similar to what we do for
    extradhcpopts and security_groups.

    Additionally, this required fixing is_address_pairs_attribute_updated() as
    it was passing (non-hashable) dicts to utils.compare_elements.

    Fix ml2 & nec plugins for allowedaddresspairs tests

    Enabling the allowedaddresspairs tests uncovered that update_port()
    was not returning the expected updated port info (still contained
    original info).
