Remove unused properties & messages #78
Description
As part of the next breaking change release, we need to make sure we go back over the protobuf and remove all unused properties and messages such as:
- WorkerHeartbeat
- worker_version
- Maybe RpcHttp
- managed_dependency_enabled - V3 breaking change: Remove managed_dependency_enabled property from FunctionLoadRequest #34
- Updating the case of the "Properties" field to snake_case for consistency (as per the style guide we follow)
