[AXON-32] (WIP) Use of RedHat UI testing framework vscode-extension-tester

* Simple working example
* clean up mocha config, add dependency to package.json
* clean tsconfig. Change test to a positive verificaiton. Note: I saw some flakes here
* Reduce flakes. Don't get the y/n question
* [AXON-32] compiling typescript tests manually
* ts test work
* lint
* normal test should ignore ui-tests
