1. Wait for 10 minutes before the 5th sr-destroy attempt …

   We already have code which retries a failed sr-destroy, when the cause is
   remaining hidden VDIs which haven't been garbage-collected yet, and it's
   enough in most cases, but not always.
   
   Sometimes, the force-gc that is triggered by SM before the delete operation
   is not enough. VDIs that look like they should be removed remain, and
   are removed only a bit later, when the normal garbage collector runs.
   
   This may be related to the fact that the forced GC operation doesn't
   coalesce VDIs, or to a special case where a recently coalesced VDI is
   temporarily protected against deletion.
   
   We add a 10 minutes wait before the 5th sr-destroy attempt, to give the
   normal garbage collector enough time to run (it should run 5 minutes
   after the last operation that creates a need for the GC to run).
