fix: Name the command explicitly so that clap_allgen can use it
Without specific command naming, the command name will default back to
the crate name nethsm-cli [1] and clap_allgen will generate completion
and man pages for a command called nethsm-cli (this is incompatible
with the nethsm executable).
