[CLI] Support passing the `soc-minima`, `soc-maxima` and `soc-targets` as sensors in the `flexmeasures add schedule for-storage`

[victorgarcia98]

PR https://github.com/FlexMeasures/flexmeasures/pull/996 introduced the possibility of defnining the soc-maxima, soc-minima and soc-targets as sensors via the API. Currently, the CLI command flexmeasures add schedule for-storage doesn't support defining any of these fields given the complexity of the resulting command (inline JSON string).

However, with the capabilities that introduced PR https://github.com/FlexMeasures/flexmeasures/pull/996, we could support passing a sensor ID to define these fields easily.
