Reinstall VM/CT: Initiate from Client Area (by ISO or TPL) BYO "Upload"

[lsthompson]

Is your feature request related to a problem? Please describe.
No current method for a client to initate a reinstall of their server.

Describe the solution you'd like
Add this to the Client Area, with warnings, and make it possible for admin to hide this.

Describe alternatives you've considered
Leaving this as ticket-only does make some sense. We need to add an ISO picker that checks for presence on all nodes.

Additional context
It makes sense given the usage of this module, however to ensure compatibility with all environments this needs optioning.

You read my mind... I literally was thinking about this today and wanted to submit this!!! +1000 for this.

In fact we're looking to add cron usage in #46 - and other providers offer BYO ISO URL which is handy.

We could align, if we set a firm expiry on a force(?) dismount of CDROM "device" and deletion of the ISO file.

Or perhaps automatic removal after its first reboot. That would require effectively monitoring the VM/CT uptime.
