Whenever we list baremetal nodes with JSON format, there's an
inconsisency between the field names specified in the command and
the field names returned in the JSON output.
Users request field names (e.g. created_at) it should return as
created_at not (e.g. Created At) pretty Json format response.
This change modifies the ListBaremetalNode.take_action() to return the
field name (columns) instead of pretty labels. So that input and output
remains consistent.
Updated all the repeative objects to match change made in the
ListBaremetalNode.take_action() and removed unused labels using Claude.
