cloudinit: move to pytest for running tests (#211)

As the nose docs[0] themselves note, it has been in maintenance mode for the past several years. pytest is an actively developed, featureful and popular alternative that the nose docs themselves recommend. See [1] for more details about the thinking here.

(This PR also removes stale tox definitions, instead of modifying them.)
