Honeycomb depends on various ODL projects (directly and via transitive dependencies). Check if all of them are necessary. Analyze especially these that include yang models, which contribute most to the HC footprint.

Some of the models might not be necessary (e.g. netconf-mdsal-notification + config dependencies - we do not use config subsystem).

It might be possible that some changes in ODL projects might be needed, e.g. moving utilities we use to separate project to reduce it's dependencies.
