* Create a "monarch" folder with everything you need to do syntax highlighting and autocompletion.
* Use this new monarch folder with existing cloudwatch sql.
* Add metric math syntax highlighting and autocomplete.
* Make autocomplete "smarter":
- search always inserts a string as first arg
- strings can't contain predefined functions
- operators follow the last closing )
* Add some tests for Metric Math's CompletionItemProvider.
* Fixes After CR:
- refactor CompletionItemProvider, so that it only requires args that are dynamic or outside of it's responsibility
- Update and add tests with mocked monaco
- Add more autocomplete suggestions for SEARCH expression functions
- sort keywords and give different priority from function to make more visually distinctive.
* Change QueryEditor to auto-resize and look more like the one in Prometheus.
* Add autocomplete for time periods for the third arg of Search.
* More CR fixes:
- fix missing break
- add unit tests for statementPosition
- fix broken time period
- sort time periods
* Bug fix
