Add an additional protected class, limit manipulation to one at a time,
and ensure future flexibility. Also makes display consistent with other
VM elements.
Matches the new node list output format with the additional header line,
as well as revamps some other aspects:
1. Adjusts the UUID to be under the name in the info output.
2. Removes the UUID from the list output to save space, because this
is generally not needed in day-to-day quick-list output.
3. Renames the "Node" header to "Current" to better reflect what
that column actually means and avoid conflicting with the parent
header.
Also adjusts the layout of the node list output to avoid excessively
long lines. Adds another header line with categories and spacing dashes
for easier visual parsing.
Also fixes up the Debian packaging such that this works how I would
want, with proper module installation while leaving everything else
untouched. Finally implements automatic installation and removal of the
BASH completion for the PVC command.
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.
Allows another way (beyond --yes) to avoid confirming "unsafe"
operations. While there is probably nearly zero usecase for this (at
least to any sane admin), it is provided to allow maximum flexibility.
