Summary:
Add the `storerequirements` feature to the repo. This means the store may have
a `requires` file, and clients must check it for any store features that they
may be missing. This allows new requirements to be added that affect the store
when the repo is shared. Currently there are no store features.
This commit adds support for the feature, and only new repos have the
requirement added. A future commit will optimistically upgrade repos to
include the requirement.
