From: Derrick Stolee <derrickstolee@xxxxxxxxxx>
The 'features' capability sends a list of "key=value" pairs from the
server. These are a set of fixed config values, all prefixed with
"serve." to avoid conflicting with other config values of similar names.
The initial set chosen here are:
* bundleURI: Allow advertising one or more bundle servers by URI.
* partialCloneFilter: Advertise one or more recommended partial clone
filters.
* sparseCheckout: Advertise that this repository recommends using the
sparse-checkout feature in cone mode.
The client will have the choice to enable these features.
RFC-TODO: Create Documentation/config/serve.txt
