Starting with GitLab 16, there is a new mechanism to authenticate the
runners via authentication tokens, so use it instead. Older tokens and
runners are also removed, as they are no longer used.
With the new way of managing tokens, both the tags and the locked state
are managed from the GitLab web page.
See: https://docs.gitlab.com/ee/ci/runners/new_creation_workflow.html
The old runners for the PM gitlab were disabled in configuration in the
last outage, but they remained working until we reboot the node. With
this change we enable the runners for both PM and gitlab.bsc.es.
