Extended user centric tooltips
### Overview
We are working on a ~"product discovery" in https://gitlab.com/gitlab-org/gitlab-ce/issues/49090. This issue serves as implementation issue of the final design.
## Solution
We're aiming to give better context to our users without necessarily opening and reading the content of other pages. To do that, we'll introduce an extended, user-centric user tooltip with the following information:
- Full name
- Username
- Company
- Location
- Status emoji and message

The following is what we could do without adding dedicated fields for job title and timezone, although I would really like to see these. It's not only useful to people working remotely, but also to large companies that are distributed globally.
