mdadm checkraid cronjob runs at the same time

Bug description:
Currently the mdadm package will install a checkraid crontab, that is the same on all installations. This is fine for a single installation, but in bigger (distributed) environments this hurts performance.
E.g. having mysql clusters on softRaid all having their arrays checked at the same moment, causes problems with availability.
An solution would / could be to add an option that will allow the
date-time to be randomized. Then this option / question can be used
where appropriate, while still retaining the option to have the static
configuration as a default.
