Non-interactive configuration is a nice property for simpler integration
use cases. eg launching from the shell is tedious with QMP compared to
CLI args.
This could be addressed though by having a configuration file to load
config from, where the config entries can be mapped 1-1 onto QMP commands,
essentially making the config file a non-interactive QMP.
