The relinker has already been robust to hardlink collisions on
tombstones for some time; this change allows ops to optionally
(non-default) enable a similar handling of other files when relinking
the old=>new partdir.
If your cluster is having a bunch of these kinds of collisions and after
spot checking you determine the data is in fact duplicate copies the
same data - you'd much rather have the option for the relinker to
programatically handle them non-destructively than forcing ops to rm a
bunch of files manually just get out of a PPI.
Once the PPI is over and you reconstrcutors are running again, after
some validation you can probably clean out your quarantine dirs.
Drive-by: log unknown relink errors at error level to match expected
non-zero return code
