Fixes #4853: Prevents 500 error loading subscription details from API.

Previous changes to ensure the use of Foreman's authentication and authorization
call resulted in the subscriptions details breaking. The find_subscriptions
method makes a call out to Candlepin which requires a current user. Thus,
the authorize method was moved higher in the filter stack and the entities
required to do authorization such as the provider, and organization were
placed prior to the authorization check.

Refs #4883: Disables SMAPs from showing up in the UI menu.

With the recent UI updates to Nutupane, and styling introductions of
Patternfly and Boostrap 3 (post enginification) as well as the backend
updates to the code base in favor of DynFlow, the Subscription Manager
Applications page is essentially non-functional. This temporary solution
is to remove the menu item for Subscription Manager Applications so as
not to give users a false sense of an existing feature.

fixes #4874 - content view filter: display validation error to user

This commit is to ensure that validation errors when
creating a new filter are displayed to the user.  The
approach used is similar/same as what is done with
creating a new content view, in that the validation
will be inlined in the form, such that the user may
correct the error and resubmit.
Fixes #4860 - reset the content view's component IDs on save failure.
fixes #4892 - content view filters & rules api - return object on DELETE

When a content view filter or rule is deleted with the API, return
the object that is being deleted.

This is correct behavior according to the API documentation and
is assumed behavior for the UI to properly update lists during
a deletion.
