All checkout requests not moving anymore

Summary: List all components in CHECKOUT status, checked out before a given date.

A typical reason for creating such report (and recreating it periodically) is to actually delete such components from staging, as illustrated in remove dead checkout requests. Here are some reasons for doing so:

• reduces the amount of components hanging around in staging libraries already for a very long time.
• it usually doesn't really hurt to delete such components from staging (one can always check it out again if it was accidently deleted).
• reduces the amount of potential CMN/ZMF audit errors (synch-flags), i.e. in case the baseline 0 content has changed since the checkout date.
• reduces the amount of parallel development notifications.
