Add vcpu_ratio definition to the IPolicy type

This will be "naturally" read in the JSON-based backends (Luxi/Rapi),
and we add explicit code for handling it in the Text backend.

Remove Node.mCpu, replaced with the ipol vcpu_ratio

Since the iPolicy contains the vcpu_ratio now, we can remove the
per-node mCpu value (which was the initial way to set this attribute).

Furthermore, we need to re-set the hiCpu value when changing the
policy....

Temporary fix for hspace's NPU calculation

hspace computes the NPU (normalised CPU units) via the
(used|pool|avail) VCPU divided by the (currently cluster-wide) max
vcpu_ratio.

However, in the future we'll have variable vcpu_ratios, so we can't
the calculation as such. We temporarily change to computing the...

Change meaning of the --max-cpu option

Instead of always overriding, we should update the nodes's maxcpu
setting only when the option is specified. Otherwise this will be read
from the cluster or from the Ganeti constant for non-live backends.

Remove obsolete constant for vcpu_ratio

This is superseded now.

Re-indent code for readability

Otherwise the docstrings for members take too many lines.

Track 'normalised' used CPUs in Cluster.CStats

This will be used in hspace for proper tracking of used/pool/unavail
npus.

Add a new type for holding allocation statistics

The current RSpec type doesn't cut it anymore (and it's used in other
places), so let's introduce a separate type for holding these
statistics.

Fix gnt-cluster modify check of passed options

… and add the disk_templates/vcpu_ratio new entries. Since the default
ispecs_* are dicts, we can't compare them to none.

Additionally, add a QA test for this case (empty cluster modify).

Export the cluster ipolicy in iallocator

And remove a strange comment (the commit which introduced it,
d61df03e, doesn't explain it). Also document these new keys in
iallocator.rst.
