[pbs-devel] [PATCH proxmox v3 3/3] proxmox-log: added tracing infra

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

Added the `proxmox_log` crate which includes the new logging infra.
Exports the `init_logger` function, which creates the `tracing` logger
that includes the default Subscriber and two custom layers. The first
layer is the syslog layer, which uses the `syslog` crate. The second
layer is the `file_layer` which uses the original `FileLogger` and
writes to a file (the tasklog). This last layer stores the `FileLogger`
as a `tokio::task_local` variable, which gets initialized at `spawn` or
`new_thread` in the `WorkerTask`.
