v15.2.7 Octopus released

This is the 7th backport release in the Octopus series. This release fixes a serious bug in RGW that has been shown to cause data loss when a read of a large RGW object (i.e., one with at least one tail segment) takes longer than one half the time specified in the configuration option rgw_gc_obj_min_wait. The bug causes the tail segments of that read object to be added to the RGW garbage collection queue, which will in turn cause them to be deleted after a period of time.
