Subject: [PATCH] MDL-27053 Code maturity info added to admin notifications
 page

The patch introduces a new string to be displayed at admin notifications
page. The maturity level message for upgrade/install reworded as
requested in the tracker.

The patch also adds a new core call to purge all caches at the beginning
of the upgrade. This must be done before the upgrade starts so that the
strings are re-fetched from the updated source and not from the on-disk
cache.
