Fix for Service requests show none with "refresh" buttons instead of selected values

[eclarizio]

This change utilizes a new option :request_view to force values that are passed in to be shown on the request review screen instead of running through the dialog again when it doesn't need to.

This will need to be combined with this PR in the main repo. to fix this specific BZ.

This is also a related BZ, where instead of seeing "" when nothing was picked, it was showing the first thing in the drop-down list: https://bugzilla.redhat.com/show_bug.cgi?id=1428133 This was a misunderstanding on my part, these BZs are not related.

/cc @gmcculloug, not sure who to assign to this one.

@eclarizio Please add before/after screenshots.

@dclarizio Dependent PR ManageIQ/manageiq#14219 is merged. Please review.

Before, notice the value says "<None>" even though I picked something when I submitted the dialog.

After, notice now it shows the value I picked (note that this does not correspond to the description of the drop-down, in this instance I think I picked "Three" but it ends up showing the actual value that was submitted, which was the integer 3).
