initial seed for tempest doc directory

This is a first bit of experiment to get a doc tree for tempest
that will publish our doc content to the web as part of a larger
QA doc guide.

Update some of the base READMEs to be a little more accurate,
now that we're going to be pushing them to the web.

Added tox [venv] to ensure that docs get built

 Configuration
 -------------
 
-At present, there are three sections to be configured: nova, environment,
-and image. The nova section includes information about your Keystone endpoint,
-as well as valid credentials for a user. It also contains logical timeouts
-for certain actions. The environment section contains reference data to be
-used when testing the Compute portion of OpenStack, as well as feature flags
-for tests that may or may not work based on your hypervisor or current
-environment. Lastly, the image section contains credentials and endpoints for
-the Glance image service.
+Detailed configuration of tempest is beyond the scope of this
+document. The etc/tempest.conf.sample attempts to be a self
+documenting version of the configuration.
+
+The most important pieces that are needed are the user ids, openstack
+endpoints, and basic flavors and images needed to run tests.
