Some tests are skipped because of the execute bit

[Julien Danjou]

The following files:

cinder/tests/integrated/test_volumes.py
cinder/tests/test_storwize_svc.py

have the +x bit set, which isn't correct and got them ignored by nosetests.

Pushing back to H2, please set back to H1 if this is milestone-critical (in which case the fix needs to land in master first and then be backported to milestone-proposed before tomorrow)

    Remove execute permissions from test files.

    Remove execute permissions from test_volumes.py and
    test_storwize_svc.py, which caused the tests defined in them
    to be skipped.

    Fixing the permissions caused test_create_volume_with_volume_type to
    execute, which fails. The cause of the failure is that
    (1) LoggingVolumeDriver doesn't implement get_volume_stats(), and
    (2) The fake RPC doesn't pass the statistics to the scheduler for
    some reason.

    Because this test doesn't test the scheduler, just change to use the
    simple scheduler and work around the issue.
