Merge branch 'replace-bootstrap-caret' into 'master'

Replace bootstrap caret with fontawesome caret

## What does this MR do?

1. Replaces all occurrences of `.caret` with fontawesome's caret (`fa-caret-down` for most cases)
2. Remove `.caret` from CSS
3. Refactored pipeline graph toggle to display the correct fontawesome caret (Had to change some JavaScript for this)  

## Are there points in the code the reviewer needs to double check?

*  Need to check if I missed any pages  or for any side effects

## Why was this MR needed?
Resolves UI inconsistency
