[pdm-devel] [PATCH proxmox-datacenter-manager v4 4/6] pdm-api-types: remote tasks: add new_from_str constructor for TaskStateType

[Lukas Wagner]

This allows us to get rid of the `tasktype` helper in
server::remote_tasks.
We don't impl `From<&str>` because those should be value-preserving,
lossless and obvious. Also, the function is not called from_str to
avoid any confusion with FromStr.

Notes:
    Changes in v3:
      - move the function to TaskStateType::new_from_str instead
        of From<&str>
