The "site_utils/deploy_server_local.py" includes a `--force_update`
option that can be used to force rebuilding the GWT client code
for either the TKO or the AFE, even if they don't appear to need it.

That's a good thing.

Unfortunately, there seems to be no easy way to force that option
to be passed during automated deploy.  Mercifully, the
"site_utils/deploy_server.py" does include a "-x" option that can
be used for the purpose.  However, that command isn't easily invoked
for the purpose:  If you reach the point where you need to force all
shards and the master, and every AFE server to update, you must
manually gather up the names of all the affected servers, and construct
the command line for yourself.

All of that is too much work:  The automated_deploy script should know
how to arrange for --force_update to be passed to every server from its
own command line.
