Fix very slow unit-test data generation in some cases

Learning, learning. It turns out that for objects with even just five
fields, generating them and filtering can be costly, especially when
the filtering is nested (as it was in this case, arbitrary1 →...

Fix one bad unit-test data generation case

It could happen that the node is generated with 0 disk available, in
which case the operation will fail due to disk issues, not CPU. Fix
this by using the recently-introduced genOnlineNode helper.

Extend node evacuation unittests

Currently they only check for change secondary, via iallocator's
relocate method. We add two separate unittests that checks all the
node evacuate modes (ChangeAll, ChangePrimary) and also the group
change request. All of these are done only for DRBD instances....

Fix a few issues in unittest data generation

This patch fixes two ugly but non-critical issues:

- the getFQDN wrongly generated only the first component as
limited-length name, the rest could be any length, and that makes
the generated name bad for display purposes...

Remove some dead code

While wondering why Cluster.tryReloc is not unit-tested, I realised
that this is no longer uses. Apparently, last summer's new IAllocator
modes and related changes have silently deprecated this function.

Fix another data generation issue in tests

Another "good" seed value manages to generate nodes with identical
names, which of course makes the sets be of smaller value than the
lists. Avoid this issue by generating unique node names.

Add a help function for generating test nodes

This abstracts the concept of "give an sane, online node" in a single
place, rather than spread around the tests. We also change the
signature for isNodeBig for easier usage.

Generate clusters with unique node names in tests

Nothing breaks otherwise in the cluster routines, but serialisation
to/from text gets confused otherwise.
