Handle restart confirmation for VMs more nicely

For the "vm modify", revamp the way confirmations are presented. Do the
edits/load, show changes, verify XML, then prompt to write and the
restart. The previous order didn't make much sense.

For any of these `--restart` triggered VM modifications, also alter how
the confirmation works. If the user declines the restart, do not abort;
instead, just set restart=False and continue with the modification.
