* Windows extension fixes/improvements
Remove error message when activating extension on non-win platforms (instead just don't do anything). Add hooks to kill child processes on exit if they haven't ended already. Formatting fixes.
* Remove shelljs
* Remove error messages from telemetry until I can follow up on whether we're allowed to send these up. Fix some issues with the exec callback - the child_process exec function returns an ExecException object instead of the code directly like the shelljs did so check for that correctly.
* ADS Windows support extension with LaunchSsmsDialog command
* Update readme
* Fix spacing
* Update download with new file location and name
* Update SsmsMin package with bits from latest RC build and addressed some comments.
* Update extension name. Add Context menu extension for launching server properties dialog. Remove params interface from public API
* Rename folder and update README
* Correct README title
* Fix a few issues and clean up some stuff.
* Update to azdata namespace
* Refactor to use async/await and add some more telemetry
* Add .bat for running extension tests (currently only Notebook) and set up launch.json with 2 new launch configs for running & debugging extension tests.
* Rename files to make it clear these aren't the integration tests
* Update launch.config too
* Fix spacing and missed file name update
* Fix some bugs in buildSsmsMinCommandArgs and add unit tests
