Add tempest test writing guide
This commit is the start of a new doc guide for helping people figure
out how to write good tempest tests. This is just a starting point for
the document and doesn't cover every aspect of writing a test case in
tempest. Right now it just covers the setupClass phase for writing
TestCases. It will be expanded upon in future commits to give a complete
guide to writing tests in Tempest.
