All the rpcs exposed by the jenga server.
The rpcs in here are used by the jenga client and build-manager. When called from jenga, versioning doesn't matter as the same executable is used on both sides. When called from build-manager, we expect build-manager to be ahead, and it should be rolled before jengas that introduce new versions.
