Improve functionality of CLAIMED CLI

[romeokienzler]

The CLAIMED CLI allows all CLAIMED components to be used from the command line in the form:

claimed <component_name:version> <parameters, ...>

claimed claimed-util-cos:0.3 access_key_id=xxx secret_access_key=xxx endpoint=https://s3.us-east.cloud-object-storage.appdomain.cloud bucket_name=era5-cropscape-zarr path=/ recursive=True operation=ls

This is implemented as an exemplar for the claimed-util-cos component but not yet generic.

Making this generic (the CLI can work with any CLAIMED component and make it available via CLI automatically) will allow to use and CLAIMED component from the terminal and in shell scripts
