Cleanup RBD contexts after exceptions to prevent potential agent crash
We noticed that when an exception occurs within the cleanup loop inside
the deletePhysicalDisk routine that the previously allocated contexts
are not cleaned up. This seemed to cause an eventual crash of the host
agent after multiple exceptions within the loop.
In addition to ensuring the contexts are always freed we also improved
the logging when exceptions do occur to include the actual return code
from the underlying library in deletePhysicalDisk and deleteSnapshot.
