CoraidDriver: typo in _login exception handler

In cinder/volume/drivers/coraid.py, _login method, if login is
unsuccessful, we try to get the message from an undefined
object "response". Instead we should be getting it from "reply".

- errmsg = response.get('message', '')
+ errmsg = reply.get('message', '')

CoraidDriver: do not call login from __init__

We should not call _login from the driver's __init__.
If the ESM is down, the constructor will fail.

- self._login()

Fetch volume_types by uuid and not by name in v2

This was left over from the UUID switch. Looking up volume_types by name
is deprecated in v1 and removed in v2.

Snapshot reservation sync calls wrong resource.

The snapshot reservations code isn't calling the
correct resource on sync (it's calling volumes).  There's
also some problems with the logic being used on the delete/clean up
that are fixed here as well.
