The patch only adds an cache_peer option to allow ICP querying of a
sibling on refreshes. The default behaviour is to only query parents on
refreshes.

It is assumed that your siblings are most likely as stale as your self.
ICP querying would then result in a stale HIT on the sibling, and the
parent is ignored. In the case of SkyCache the situation is very
different than a normal sibling relation. They use this method to push
cache content to your cache from a sibling (the SkyCache server).
