gRPC Request Protection
This is an optional feature meant to further secure module intercommunication.
When enabled, Conduit and all of its modules make use of a common secret string to sign their outgoing
and verify the authenticity of their incoming remote process calls.
This feature should not be used as a replacement for deployment network level whitelisting.
It does not encrypt gRPC requests either.
To enable it, simply specify a secret string to GRPC_KEY for every single Core or module instance you're going to deploy.
