End to end automated tests run on Github workflows (#384)

* WIP for automated integration test

* See if it runs under a workflow

* Support running test locally as well as a workflow

* Use already downloaded repo to build. Do not re-clone

* Add comments

* Update to support new default config file

* Split out different test suites

* Add test for chat

* Always run test with config-default and ignore local config file

* Remove the build workflow because the end to end test does that now
