In this example, the instance policy for disks prevents allocation
of more than one instance per node. The test verifies that tiered
allocation still respects this and doesn't attempt to place policy
violating instances on the cluster.

Both tiered and standard allocations are tested, with a single and a double
min/max instance specification.

htest/data becomes test/data/htools (basically reverting commit
8feabc89

), and htest/* becomes test/hs/*.

Most changes beside the rename are trivial s/…/…, with the exception
of autotools/run-in-tempdir, which needed some more changes now that
test/ is not just Python files:

- test/py is still being copied
- test/hs moves from individual symlinks to entire dir symlink
- test/data is symlinked in its entirety

Checked with make distcheck, pep8 and pylint, so at least VPATH builds
are OK.
