Subject: [PATCH] Begin work to send resize to remote

While we do not have a path forward for auto-resize in SOL consoles,
we can provide the capability for ssh consoles.  The CLI being enabled
is of course nice, but running ssh directly is still suggested in such
a context and ultimately the Web GUI will be the most prominent
consumer of the information.
