[pbs-devel] [PATCH proxmox-backup 0/3] backup client progress log interval

[Christian Ebner]

These patches allow to specify a time based or size based interval
for progress log output as generated during `proxmox-backup-client
backup` runs.

The client is extended by an optional `progress-log-interval`
parameter, which allows to set the interval as `TimeSpan` or
`HumanByte` parsable input string, depending on the variant prefix.
If set to `none` the progress log output is disabled, if no prefix is
specified, a time based interval is assumed. Lastly, if the parameter
is not given, the default 'time:1m' is used.

Examples for client invocations are:
- no progress logging:
  `proxmox-backup-client backup root.pxar:/ --progress-log-interval=none`
- time based progress logging with 1min 30s interval
  `proxmox-backup-client backup root.pxar:/ --progress-log-interval="1m 30s"`
  `proxmox-backup-client backup root.pxar:/ --progress-log-interval="time:1m 30s"`
- size based progress logging with 512MiB interval
  `proxmox-backup-client backup root.pxar:/ --progress-log-interval="size:512MiB"`

Lower limits are set to 1s and 100MiB for the corresponding variant in
order to prevent excessive log output.

  api-types: client: add type to specify progress log interval
  client: progress log: factor out log message generation
  client: progress log: allow to specify backup log interval
