This patch modifies the existing combining code in imagetools create to
provide better support for multiple repositories down the road.
Specifically, the code should no longer rely on a single repository
being used for all sources and tags, and should resolve descriptors in
their relevant repositories.

containerd pusher can’t handle this case atm so we
need to make sure we always create a new resolver
for each name.
