Hammer CLI

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1417726

Description of problem:

Foreman part of hammer cli uses parameter --order="<FIELD_NAME> <DIRECTION>" for ordering results. Katello part uses two parameters --by="<FIELD_NAME>" and --order="<DIRECTION>"

For example compare

hammer architecture list -h

and

hammer repository list -h

Apart from the above there are additional issues:

• in Katello commands --by and --order seem to have no effect (probably related to bz 1138262)
• in Foreman commands there's no validation of the direction and API silently falls back to 'ASC'

Version-Release number of selected component (if applicable):
hammer-cli-foreman 0.9.0
hammer-cli-katello 0.3.0

Actual results:
There are various parameters for ordering results, some of the dysfunctional.

Expected results:
Hammer should provide unified commands for ordering fields. Probably only --order should be used.
