- make `logging.GetLogger(ctx, Subsys)` the authoritative `logger.Logger` factory function
- the context carries a linked list of injected fields which
`logging.GetLogger` adds to the logger it returns
- introduce the concept of tasks and spans, also tracked as linked list within ctx
- [ ] TODO automatic logging of span begins and ends, with a unique
ID stack that makes it easy to follow a series of log entries in
concurrent code
- ability to produce a chrome://tracing-compatible trace file,
either via an env variable or a `zrepl pprof` subcommand
- this is not a CPU profile, we already have go pprof for that
- but it is very useful to visually inspect where the
replication / snapshotter / pruner spends its time
