Add support for inserting stripe extents into the raid stripe tree on completion of every write that needs an extra logical-to-physical translation when using RAID. Inserting the stripe extents happens after the data I/O has completed, this is done to a) support zone-append and b) rule out the possibility of a RAID-write-hole.
