Hammer CLI

Printing the descriptions at new lines for long options could improve the readability:

Options:
    --label LABEL                 Content view label
    --name NAME                   Name of the content view
    --organization ORGANIZATION_NAME 
                                  Organization name to search by
    --organization-id ORGANIZATION_ID
    --organization-label ORGANIZATION_LABEL 
                                  Organization label to search by
    --repository-ids REPOSITORY_IDS 
                                  List of repository ids
    -h, --help                    print help

Can be easily changed by overriding 'add_list' in our help builder. See the links for details:
