I created a vscode extension to run scripts within the script, after_script and before_script sections in a child process and output it in vscode panel.

That should reduce feedbacktime for ci-jobs. Also I integrated shellcheck into such sections while keeping yaml syntax in tact.

Check it out, reviews and feedback very appreciated! :)

I will probably integrate gitlab-ci-local in the future to make it even easier to start and test jobs from vscode.
