Fixes #4657: Removes Katello current user setting and moves consumer
authentication checking to the proxies controller.

Previously, the API controller was attempting to handle authentication for
standard users and consumers across all controllers. After moving all consumer
routes and functionality to the Candlepin proxies controller, client authentication
should be handled within the context of that controller and authentication/authorization
controller relegated to the underlying Foreman framework.
fixes #4708 - Prefix ambiguous id in query
Fixes #4713 - don't store results for copy/remove content actions

The data are not used in the code so no need to consume
storage/memory on that, as there might be quite a lot of data for
large repos.

fixes #4726 - update hostgroup activation keys to support katello v2 apis

When a user selects a lifecycle environment & content view,
a request is sent to the server to retrieve the activation
keys associated with the selected env+view.  This allows the user
to choose from those via the Activation Keys pane.

This commit is to fix the behavior which previously
performed multiple requests to the server to retrieve
environment, content view and then keys.  This alters
that behavior to perform a single request for the keys.
