rbd: add a test to verify that encrypted volumes can be resized
Add a test to verify that an encrypted volume can be resized to the desired unencrypted size similar to how the rbd command line tool is documented as able to do. Fixes: #972 Original-Version-By: Will Gorman <will.gorman@gmail.com> Signed-off-by: John Mulligan <jmulligan@redhat.com>
