GDK Cells Manager to configure additional cells Session Prefixes
In order for the Cells to work, the HTTP Routing Service needs to direct the User Requests to the correct cells using the Session Cookie Value Prefix.
Each GitLab Cell needs to configure the Session Cookie Prefix based on the Cell name.
GDK now allows adding multiple Cells: https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/main/doc/howto/cells.md#setting-up-cells-locally, but these additional GDK Cells don't configure the session cookie prefix yet.
What this issue is meant to implement, is to add the Session Cookie Prefix when we run up
on the additional cells. Probably this should be implemented here:
https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/main/lib/cell_manager.rb?ref_type=heads#L101
