As discussed offline, the new node-change mode could be used for
evacuation, but it's not directly useful as it returns a list of
opcodes; therefore, we need to partially revert commits fbe5fcf6 and
5b53ca79 that removed it (and multi-evacuate, which remains removed).

The new version of relocate is actually just a wrapper over the
tryNodeEvac (which does the node evacuate); we run that and then we do
some extra checks that the nodes we got from that function are
consistent with the instance's new state.

During instance installations, you do not want the instance to reboot
and start again with the same parameters, as that will most likely
re-start the install process. Therefore, when the instance requests a
reboot it should instead shutdown. This flag allows this to be
controlled.

The OS scripts currently run with the whole noded environment; this is

This removes:

- the check in backend that such OSes have a variants file or if it

Currently, hspace can only output a machine-readable format that
(while detailed) is hard to parse quickly by people. This patch adds
(and enables by default) a human-readable output that shows the most
important metrics in a simple format.

Most of the work of the patch is in moving the display of various
metrics from the 'main' function to separate functions, each of which
can output either a machine or human intended format.

The patch also corrects a bug in the CPU efficiency display: before,
the efficiency was computed as instance virtual CPUs divided by total
physical CPUs, which is almost always supra-unitary. More correct is
to divide by the total virtual CPUs, which shows a more meaningful
number (when the p-to-v CPU ratio has been defined correctly).
