removes the nova-volume code from nova

This removes the majority of the nova-volume code from the codebase.
It updates relevent config options to default to cinder. It updates a
number of existing tests that were depending on code that was removed.

A few things still need to be removed:

 * volume/driver.py & volume/iscsi.py
   These files are used by the libvirt volume driver tests. These
   tests should be updated to mock the relevant calls.

 * scheduler/simple.py & scheduler/multi.py
   These files should no longer be necessary so they can be removed
   in a subsequent patch

 * exception.py cleanup
   Once the above files are removed there are a number of unused
   exceptions which can be removed

 * database calls and database tables
   The database calls have not been removed and the tables have not
   been dropped. This can be done in a separate migration

 * additional config options and nova.conf.sample
   There may be a few extra config options that can be removed and the
   conf sample can be regenerated
