    Script to remove duplicated port bindings

    A new script to remove the duplicated port bindings was added. This
    script will list all ``ml2_port_bindings`` records in the database,
    finding those ones with the same port ID. Then the script removes
    those ones with status=INACTIVE. This script is useful to remove
    those leftovers that remain in the database after a failed live
    migration.

    "dry_run" mode is possible if selected in "[cli_script] dry_run"
    boolean config option. The duplicated port bindings are printed in
    the shell but not deleted.
