* Added new docker-compose files to aid with ui test development as
as well as running ui tests against upstream.
* Changed the tests to use pytest base url. This allows us to use
the verify option to wait for the server to be created and setup
before beginning the tests.
* Added setup-docker.sh script to config the docker redash databases
and setup the redash instance for testing.
* Added a docker entrypoint to allow for calling test command from
the command line. This will help with CI.
