[oozie] Hide Oozie specific workflow properties

Oozie parameters need to have hide flag. Some system options (for example oozie.use.system.libpath, oozie.libpath) should't be shown when workflow is submited.

Now it's hardcoded for one parameter:

<div class="fieldWrapper">
<div class="row-fluid
% if form['name'].form.initial.get('name') == 'oozie.use.system.libpath':
hide
% endif
">
<div class="span6">
${ form['name'].form.initial.get('name') }
</div>

Also it would be great to be able to make parameter as only selectable from the list.
