Show explicit message when hspace fails to alloc

Currently, in the human-readable mode, hspace doesn't show any
messages when no instances can be allocated in tiered-alloc mode. This
is confusing, so let's add an explicit message.

Obey instance policy in allocation routines

This currently checks the minimum/maximum sizes and the disk
template. Unittests will come later.

Set group policy on nodes

In order to be able to use the group policy during allocation, we have
a few choices:

- pass the group policy as a separate argument to all involved
functions, or
- add the policy as an attribute to nodes, or
- add the group (not only the group index) as an attribute to nodes...

A trivial optimisation in Loader.mergeData

During loading, we can eliminate some intermediate data
structures. This only matters for big clusters, and even there it's
less than 1% less memory allocated, but still, it's a no-brainer.

Trivial performance optimisation

This is not in the hot-path, but still, no sense in doing O(n) instead
of O(1).

Add ipolicy attribute to group objects

This is straightforward; as before, so far the text and simu backends
have no way to use a non-default ipolicy.

Furthermore, we do some unit-test preparation for future changes
(these seem a no-op for now, but they are needed for later patches)....

Enable Eq instances for TH-built objects

This is needed for the next patch.

Switch hspace to read the disk template from the cluster

The default disk template is the first enabled template.

Read the disk templates part of the ipolicy

The default value is badly defined (hardcoded defaults)…

Move DiskTemplate definition around

This is needed since we'll need the DiskTemplate definition in the
IPolicy one.
