Ensure request_spec can be serialized.
request_spec includes some objects that must be converted to primitive
types to ensure they can be serialized by any of the rpc drivers. In
this case, it's the volume type. It's a sqlalchemy model.
to_primitive() will ensure that it gets converted to a dict so that it
can be serialized for messaging.

Add admin only action for force detach
This action calls the same methods nova would after it successfully
detaches a volume. By exposing it to the administrator it makes it's
easier to repair un-syncronized state between services. Generally when
the host is no longer attached, but the volume state is wrong.
Future work: The Iscsi based drivers don't seem to use
initialize_connection and terminate_connection to create the export for
the volume. This would be more useful with drivers that do that.
I added the force parameter to terminate_connection for drivers that may
want to differintiate between a normal terminate and the force detach.
Future Nova work: Nova will want an admin action to update the bdm
tables - today it's a bit of nova-manage shell work.
The openssl popen call to verify the token returns an error code
of 2 when a file doesn't exist. Normally this is caught and the
relevant file is downloaded, but monkeypatching os causes this
error code to be eaten and cinder to return a 401. Note that this
is likely a race condition that depends on exactly when greenthreads
are switching that is causing the return code from Popen to get
overwritten.
It is possible that this is exposing an underlying bug in eventlet
but the workaround is simply to make sure that we don't monkeypatch
os.
