Jonathan Gramain 7f98c7b543 bugfix: S3C-2987 update listing algo for v0v1, v1mig migration steps
The v0v1 migration step (keys are both in v0 and v1 format) and v1mig
(keys in v0 are being deleted) both use the same logic than the plain
v1 vformat, because all v1 keys exist hence the listing can benefit
from the v1 enhancements in those migration steps.

Jonathan Gramain 87bdac0391 bugfix: S3C-2987 update listing algos for v0mig vformat migration state
Update the listing algos to work for buckets in v0mig state.

The main particularity of v0mig is to require a listing of two
disjoint key ranges: before and after the V1 prefix, to gather the
same listing than V0 without listing the V1 keys being migrated.

It will require a change in metadata RepdServer to allow for the
disjoint listing, triggered by the 'serial' attribute sent back in the
listing params.
