Fix include_task_info for `transfer show --show-instances-data`

The transfer's `info` is only returned with
`include_task_info=true`, which the CLI never sent,
so `--show-instances-data` failed with "ERROR: info".
Add an `include_task_info` flag to
TransferManager.get and set it when the option is passed.

Update user script help strings

* specify the supported phases and which one is the default

  can be omitted in order to unregister it
