changegroup: add `delta_base_reuse_policy` argument
The argument available through function from changegroup.apply to
`revlog.apply` allow to override the revlog configuration in terms of
delta-base-reuse policy when searching for a delta to store a revision.
It will be put to use in the next changesets.
