    Fixing lost vlan ids on interfaces

    Sometimes a vm gets its tap interface unset and reset too fast to be caught in
    an agent loop, and its vlan tag was not reset.

    We now detect if an interface loses its vlan tag, and if it happens the
    interface will be reconfigured.

    Since the TAG ID is only available via the "Port" table (in the 'tag' column),
    we couldn't reuse the get_vif_port_set() method's run_vsctl call which queries
    the "Interface" table, and needed a specific run_vsct call to the "Port" table
    in the new get_port_tag_dict() method.
