Fix saving tz aware datetimes in Versioned Objects
Currently we cannot save date fields in Versioned Objects because they
are timezone aware and our database is not.
If we look at our objects definition, we are not giving any value to
tzinfo_aware argument, so it takes DateTime default value (True).
In our sqlalchemy model definitions we are defining our datetime fields
as Column(DateTime) which will take sqlalchemy default: class
sqlalchemy.types.DateTime(timezone=False)
In most cases we are accessing those fields directly through the DB
methods, so we don't see the problem, but if we were to modify any of
those fields using versioned object, for example scheduled_at, and then
save the object we'll get an exception:
File ".../sqlalchemy/sql/type_api.py", line 278, in compare_values
return x == y
TypeError: can't compare offset-naive and offset-aware datetimes
Because we are trying to save a timezone aware date to a timezone
unaware DB field.
Following Dan's advice we create a specific cinder_obj_get_changes,
instead of overwriting obj_get_changes, that returns all datefields as
timezone naive UTC datetimes ready for saving.

Set encrypted key in connection_info during initialize
There are encrypted volume tests in Tempest which are passing
in the ceph job but the encryption providers in nova (luks and
cryptsetup) are not actually being called in nova because the
'encrypted' key isn't being set in connection_info for the Rbd
volume driver, and nova is keying off that value to determine
if it needs to run it's encryption providers.
So the tests are passing in the ceph job but it's a total false
positive and the API should actually fail - either the cinder
API to create the encrypted volumes if the Rbd volume driver in
Cinder doesn't support encryption, or the volume attach call in
nova if it can't encrypt the connected volume, either way the
test should fail until that support is baked into nova.
I'm not aware of any kind of 'supports_encryption' or 'encryptable'
capability flag for cinder volume drivers, but that might be
needed for the volume create API to fail if trying to create a
volume from an encrypted volume type where the volume driver
itself doesn't support encryption - but maybe it's only a nova
problem since nova has the encryption providers.
This is fixed generically in the VolumeManager's
initialize_connection method where we check for the encrypted
flag being set in the volume driver method and if not, the
manager sets it based on the volume.encryption_key_id value.
We do this globally since there are other volume drivers besides
rbd that aren't setting the encrypted key in connection_info,
but we test rbd in the gate via the ceph job so most of the
bug tracking is around validation of the ceph job.
