This time we plan to post multiple patches. In order to put them together, we created BP
I posted a test verifying the operation of the existing Nova API in a multi-cell environment.
Please review.

> We don't really need a blueprint for this work. It would be good to know what gaps in existing testing you think exist. And where do you plan on implementing these tests? In the nova/tests/functional tree or somewhere else? We already have a lot of tests which are using a CellDatabase fixture which allow us to create multiple cell mappings for tests in the API.
> If you're considering Tempest, tests there wouldn't really be appropriate because to the end user of the API, they should have no idea if they are talking to a cloud with multiple cells or not, since it's really a deployment issue.
> What we don't have today in our CI testing, and that we need someone to work on, is running a devstack multi-node setup with at least two cells. This likely requires some work in the devstack-gate repo to configure devstack per node to tell it which cell it is.
