Location aware search

Closes #3400 #14217

Introduces suggestion grouping on the search box and adds the ability to the user to remove the location to search on.


**Notes**
- Suggestions are now grouped by category.
- Suggestions are displayed when no location is set.
  - Would be great to provide suggestions for the specified location which could be a project or group.
- A location is set from the server for projects/groups related urls.

**Default Apparence**
