Previously, editing nodes to contain a new set of driver options or
config files was unsupported, and silently dropping them. In this patch,
we update with these, as well as add a new warning message that any new
options may not taken into account until the builder restarts (which
may apply to the flags, platforms and endpoints as well).

This builds on the added warnings from initialized builders, now
erroring the command, and additionally attempting to revert to the
previous configuration.
To preserve the previous configuration, we add a deep Copy() function to
the NodeGroup and Node so that we can easily restore it later if we
encounter a failure.
