When a repository does not yet exist during a fetch, i.e. a clone,
then only delegates are being fetched.
Augment Namespaces::Many to hold the trusted and optional delegate peers
separately. Doing so allows the construction of the variant without
the repository existing, but tracking relationships existing.
This variant can then be used to build refspecs for both the trusted
peers and delegates when doing a cloning fetch.
