MDL-67898 check: Add check admin setting
This admin setting allows you to display a check anywhere in the admin
tree. It uses a webservice to execute the check, so the impact on the
admin tree performance is as low as possible.
Checks do not necessarily need to be registered in the plugins callback
to be shown here, allowing customisation of what is shown in the
settings versus the reports.
