ConsistencyGroupsClient does not set api_version

[Chuck Fouts]

The ConsistencyGroupsClient does not set the api_version used by the inherited RestClient. During a post the api_version defaults to "v1" which in turn results in a 404 response.

Setting the api_version = 'v2' fixes this issue.

Looks like this was supposed to be opened against tempest.

Appears to be working right in current tempest, so closing this.
