This test uses a non-existing config value "file-storage-dir" and fails.
Fixing it by using the default value, which is currently what qa does.

The rename instance test performs an lvm-specific check for tags on the
instance volume. This should be in the future abstracted *inside* the
template class, and not explicitly called from qa.

This would allow other disks to perform the checks that make sense for
them. In the meantime though, we just make the same check only when the
backend storage for the instance is lvm-based.

Add a simple walk through the intended use case of
gnt-instance modify --new-primary for the disk template
file. The tested scenario is shutting down an instance,
manually moving the disk to the new node, setting the
new primary, and starting up the instance on the new
node. It is also verified that the operation is rejected
while the instance is still running on the old node.

This patch adds the currently known and used storage methods to the
constants.py file. Note that storage types are different from disk
templates. For example both disk templates, drbd and plain, use lvm
storage types.

The rapi documentation asserts that valid storage types are limited
to lvm and file. With the extension of storage types, this is not true
anymore, but the implementation of listing storage units is not
implemented for the new types. We disable the assert for now, adding
a fixme to extend it once the listing of storage units is extended
for the new types as well.

'gnt-node list-storage' currently does not support any other storage
type than 'lvm' and 'file'. We limit the QA to storage types that are
currently implemented for this operation.
