GITHUB_ACTION_PATH + GITHUB_ACTION so that we can run scripts for Composite Run Steps (#615)

Browse Source 
* Add environment variable for GITHUB_ACTION_PATH

* ah

* Remove debugging messages

* Set github action path at step level instead of global scope to avoid necessary removal

* Remove set context for github action

* Set github action path before and after composite action

* Copy GitHub Context, use this copied context for each composit step, and then set the action_path for each one (to avoid stamping over parent pointer GitHubContext
