Allow passing LabeledArrays as commandline options

* Protect from long default values in `--help` output by adding a size
  limit and manually adding reduced string representation
* Use pre-existing to/from JSON conversions to dump and retrieve
  labeled arrays in command line
* Allow passing only values if the labels do not change from defaults
* Test options retrieval for the driver and devices
