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.
