This object is responsible for registering all concepts, creating arguments for the concepts, and creating a RuntimeParser which will be responsible for parsing the concepts.

This method adds a concept to the ConceptManager. It does not immediately have any effect on the command's argparse parser. Args: concept: base.Concept, an instantiated concept.

For each concept, the Attribute() method is called, and all resulting attributes and attribute groups are translated into arguments for the argparse parser. Additionally, a concept-specific RuntimeParser is created with all of the resulting attributes from the first step. (This will be responsible for parsing the concepts.) It is registered to the argparse parser, and will appear in the final parsed namespace under CONCEPT_ARGS. Args: parser: googlecloudsdk.calliope.parser_arguments.ArgumentInterceptor, the argparse parser to which to add argparse arguments.
