Is this more of an example of how to add new fields or is custom_data_1 already used?

Ah, it's used by my perf. I might come back to this and give it a meaningful name, but I thought to keep it agnostic.

This PR includes: - Attachment of PPM to cluster controller now use Networking - PPM observes partition processor status through a buffered watch mechanism - PPM can now send control messages (unused at this PR) to processor for future use. - PPM collects state information from running processors. This will be used in a follow PR to response to controller requests about partitions. Cluster controller grpc service is kept for external tooling integration (CLI, etc.)
ClusterState is a new data structure maintained by ClusterController. ClusterState is established by a scatter-gather request (GetProcessorsState) to all workers. For every worker, partition processor manager is the entity responsible for responding to GetProcessorsState requests, it keeps taps on running partition processors via a set of tokio watches. This PR is a snapshot in time of progress done on this component, this is far from complete but it's best to merge the current progress until we circle back to it in a week or two.
This also changes the loglet API to accept Bytes to avoid duplication of serialization across loglet implementations. This holds the current invariant that payloads are opaque to loglets.
