This icommit adds several changes related to the same topic
- resetting a Runner registration token:
1. On Project settings page it adds a button for resetting the
registration token and it removes the Runner token field
that was confusing all GitLab users.
2. On Group settings page it adds the same button for resetting
the registration token.
3. On Admin Runners settings page it moves the button to the same
place as in Project and Group settings and it changes slightly
the page layout to make it more similar to Group and Project
setting pages.
4. It refactorizes a little the partial that prints runner
registration description. Thanks to this Project, Group
and Admin settings of the Runner are re-using the same
code to generate the button.
5. Updates the translations of changed text.
