[pbs-devel] [RFC proxmox-backup v2 0/2] Tasklog rewrite with tracing

[Gabriel Goller <g.goller@proxmox.com>]

Removed the task_log! (and friends task_warn!, task_debug!, etc.) macro
and introduced the `tracing` crate. We now initiate the tracing crate
using two Layers, first the syslog layer (using the `syslog` crate) and
the `file_layer`. The file_layer uses the original `FileLogger`.

To write to the task logs from the worker threads and tasks, we now
have a task_local logger (and warning counter) in the file_layer, which
will get instantiated when a task/thread is created. This means that
when we call `info!` or any other `tracing` log macros (with the "tasklog"
attribute), it will get the file_logger from TLS and write to the file.

Most notable changes since version 1:
 - Remove the 'tasklog = true' attribute and infer the context
    - Wrap the worker_thread or worker_task in a span with name
      'worker_task'
    - All events in the span with name 'worker_task' get logged to the
      file_logger, everything else goes to syslog (Error events go to
      both)
 - Remove the `Option<>` around the `FileLogger` in TLS
 - Clippy fixes
