CE-2164: Modify autocomplete loading in Template tool
There are 2 components where are autocompletes/dropdowns:
- admin page: where admins can change the repositories
- instance generation: where users can select the proper template-, and config revisions to generate instances
Modified the FIRST one (admin) to not to show all repositories when opening up the dropdown (will show the repos when user starts typing) - I don't think it would be a nice UX if we would not show the tags/commitIDs to the users.
Deployed it to the DEMO environment.
