Macpie/custom tracing

[macpie]

• Add a tracing_subscriber that is re-loadable via a file (takes the content of the file and turn it into an EnvFilter)
  • File can be created
  • File delete will go back to original filter from settings (same for empty file)
• Gives negative feedback when file content cannot be parsed as an EnvFilter
• Functions to create tracing spans around GRPC (tonic) or HTTP (axum) including latency
• GRPC or HTTP are lib features
• Include one example of use in ingest/server_mobile
• Filter ex custom_tracing=info,mapper_ingestor[tracing{uri=/session_init}]

Since this custom tracing is spawning a process off is tokio respecting the shutdown signals from the thing that instantiates these being shutdown or do these need to be run underneath the task manager in order to shut down as expected with a ctrl-c?
