Change the meaning of the N+1 fail metric

Currently, this metric tracks the nodes failing the N+1 check. While
this helps (in some cases) to evacuate such nodes, it's not a good
metric since rarely it will change during a step (only at the last
instance moving away). Therefore we replace it with the count of...

Introduce per-metric weights

Currently all metrics have the same weight (we just sum them together).
However, for the hard constraints (N+1 failures, offline nodes, etc.)
we should handle the metrics differently based on their meaning. For
example, an instance living on a primary offline node is worse than an...

Allow balancing moves to introduce N+1 errors

This patch switches the applyMove function to the extended versions of
Node.addPri and addSec, and passes the override flag based on the state
of the node that we're moving away from.

Introduce a relaxed add instance mode

In case an instance is living on an offline node, it doesn't make sense
to refuse moving it because that would create N+1 failures; failing N+1
is still much better than not running at all. Similarly, if the
secondary node of an instance is offline, meaning the instance doesn't...

Remove obsolete Container.maxNameLen

This was only used in one place (hbal), and is obsolete by the change to
the dual name/alias structure.

hbal: print short names in steps list

This was a regression from the name handling changes, as we started
using the original names for the solution list (which is not designed
for parsing/feeding back into ganeti).

Remove an obsolete function

printSolution is no longer used, as we print the solution iteratively
now.

Allow '+' in node list fields

When the field list is prefixed with a plus sign, this will extend the
default field list, instead of replacing it entirely.

Update the node list fields

This patch renames the pri/sec to pcnt/scnt, and adds the real primary
and secondary instance lists, the peermap and the index of a node as
selectable options.

Cleanup a node's peer map when possible

If the last secondary instance of a peer is deleted (detected by the new
peer memory value being equal to zero), then the pair (pdx, 0) should be
deleted completely. This is not optimization per se, but rather cleanup...
