Add status message from within user menu

Problem to solve

https://gitlab.com/gitlab-org/gitlab-ce/issues/35463 introduces status messages for GitLab users. Status based on an emoji and a message can be added via the profile preferences settings.
To make this feature more discoverable and frictionless, let's add the option to set a status directly to the user menu.

Solution

user menu

• If no status is set, menu item should be Set status
• If a status is set, menu item should be Edit status
• Modal title should always show "Set status" regardless if a status has been set yes or no

No status set yet

Status already set
