This patch adds a helper command: save-ofports. The command
will o/p a shell script that will set the 'ofport_request' column
of the interface table with the value of the corresponding ofport.
This command takes a list of bridges as input and will be used by
a future commit to restore the ofport value across force-reload-kmod.
Issue #13556
