Tech debt - capitalize monitor javascript constants
Follow-up comment from a merge request. https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/29691#note_191223492:
Outside the scope of this, but should constants be capitalized?
The constants in question are in this file: https://gitlab.com/gitlab-org/gitlab-ce/blob/36a729f05f1b9c2b3935b9d121b8fe3172ce5cc1/app/assets/javascripts/monitoring/constants.js
This is a small amount of work, and would increase consistency with the rest of the codebase. (Note: not mentioned in the js style guide as of yet).
