Description of problem:

If you go to a system details page and click on the software > errata tab, and
select some errata for application - the errata application will always be
scheduled for ASAP. there is no schedule widget for their application. this is
of particular concern for customers with osad on their Satellites as the erratum
will get applied immediately.

contrast this with the (1) ssm > schedule errata updates ui, where you can
schedule multiple errata updates for multiple systems and get a schedule widget
for it or (2) errata > affected systems ui, where you can schedule one erratum
updates for multiple systems and get a schedule widget.

attaching a screenshot of what the confirm errata application screen looks like
for the SDC. a schedule widget should probably be added to this page.
