    Improve "OVSFirewallDriver.process_trusted_ports"

    FirewallDriver.process_trusted_ports" is called with many ports,
    "_initialize_egress_no_port_security" retrieves the VIF ports
    ("Interface" registers in OVS DB), one per iteration, based in the
    port_id. Instead of this procedure, if the DB is called only once to
    retrieve all the VIF ports, the performance increase is noticeable.
    E.g.: bridge with 1000 ports and interfaces.

    Retrieving 100 ports:
    - Bulk operation: 0.08 secs
    - Loop operation: 5.6 secs

    Retrieving 1000 ports:
    - Bulk operation: 0.08 secs
    - Loop operation: 59 secs
