createmarkers: allow to pass metadata for a marker only
The `metadata` argument only allow to specify metadata for all new markers. We
extension the format of the `relations` argument to support optional metadata
argument.
The first user of this should be the evolve extension who want to store parent
information of pruned changeset in extra (until we make a second version of the
format)
