Trove Mgmt List Commands Failing (Storage, Hosts, etc.)

[Steve Leon]

The management command 'storage' raises an error when being used.

Storage list returns a 'Client' object has no attribute 'rdstorage' (HTTP 500) from the client.

In the reddwarf-api log, the following error is observed:

```
In looking at the code:

https://github.com/openstack/trove/blob/7ab80b554dde5f1f1e61b6a8c45492c5ac27ed6b/trove/extensions/mgmt/volume/models.py#L48

It becomes clear that nothing is setting the client.rdstorage attribute.

But if you grep (or GitHub) search trove + trove-integration + python-troveclient, nothing ever sets it. The only reference is in Tests, in which it used to mock api requests:

https://github.com/openstack/trove/blob/7ab80b554dde5f1f1e61b6a8c45492c5ac27ed6b/trove/tests/fakes/nova.py#L750

This problems exists for "quotas list", "hosts list", "storage list", etc.

rd* are rackspace specific mgmt apis. They need to push that functionality into nova before these calls will actually work.

[Nikhil Manchanda (slicknik)]

The new trove client doesn't have these management commands, so this bug is Invalid. There will be a separate BP to add management commands for the trove client.

This was cited on the openstack-dev list as an ongoing issue:

[Amrith Kumar (amrith)]

For the reasons Nikhil mentioned in #3 above, this is Invalid.
