Pulp

Description of problem:
--fields option for pulp-admin doesn't except names of repo's fields as they are written in the output, i.e. with capital letters and spaces

1) pulp-admin rpm repo list --fields "id,description,display name" doesn't work
but
pulp-admin rpm repo list --fields "id,description,display_name" is ok

2) pulp-admin rpm repo list --fields 'Id,Description' doesn't work
but
pulp-admin rpm repo list --fields 'id,description' is ok

Suggestion: It's not obvious that repo's fields should be written in lowcase and with underscore instead of space. If it's difficult to fix, let's put an example in --help output:

pulp-admin repo list --help

Command: list
Description: lists repositories on the Pulp server

Available Arguments:

--summary, -s - if specified, a condensed view with just the repository ID and
                name is displayed
--details     - if specified, detailed configuration information is displayed
                for each repository
--fields      - comma-separated list of repository fields, for example   
                "id,description,display_name,content_unit_counts"; if
                specified, only the given fields will displayed

Version-Release number of selected component (if applicable):

rpm -qa | grep pulp-server
