Description of problem:
Couldn't find any working combination of the --by or --order parameters that would allow me to sort the output.

Version-Release number of selected component (if applicable):
$ rpm -qa | grep hammer
rubygem-hammer_cli_foreman_tasks-0.0.3.4-1.el7sat.noarch
rubygem-hammer_cli_katello-0.0.7.15-1.el7sat.noarch

rubygem-hammer_cli-0.1.4.11-1.el7sat.noarch
rubygem-hammer_cli_foreman-0.1.4.14-1.el7sat.noarch
rubygem-hammer_cli_gutterball-0.0.1.2-1.el7sat.noarch
rubygem-hammer_cli_import-0.10.17-1.el7sat.noarch
rubygem-hammer_cli_foreman_discovery-0.0.1.10-1.el7sat.noarch
rubygem-hammer_cli_foreman_docker-0.0.3.7-1.el7sat.noarch


How reproducible:
Always

Steps to Reproduce:
1. Try one of the below tentatives:
$ history | grep 'hammer content-view version list'
[...]
  289  hammer content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --order 'version ASC'
  290  hammer content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --order 'Version ASC'
  291  hammer content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --by version --order ASC
  292  hammer content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --by version
  293  hammer content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --order name DESC
  294  hammer content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --order 'name DESC'
  295  hammer content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --order Name
  296  hammer content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --order DESC

Actual results:
None of them works, --by on its own doesn't seem to make any difference, --order leads always to an error of the kind "the field 'xxx' in the order statement is not valid field for search"

Expected results:
The --help output expects clearly what is expected and how it relates.
There is a clear combination of parameters on how to sort such lists.

Additional info: (debug output of hammer, notice that the order parameter is sent twice, as part of the sort and outside of it, looking at apidoc, it doesn't sound right)

$ hammer --debug --csv content-view version list --content-view cv-acme-soe-demo --organization Default_Organization --by name --order "name ASC"
