Fixes #6211,BZ1102521 - Requiring a user to ping pulp_auth

It looks like the code didn't properly set User.current so Katello.pulp_server
was nil. This code checks for a user in the controller. Also, it handles the
case of no user by skipping the pulp_auth check which needs remote_id from a
user.
Fixes #5555 - fix org update action's apipie param

In the OrganizationController v2 update action, the param_group
resource contained hash named resource. This was not substituted
for organization. As a result hammer-cli-katello, through
api-bindings, was incorrectly expecting and passing resource instead
of organization to the update action. Subsequently no
organizations were being updated.

The param_group was redefined on the update action so that the param
hash could have the correct name, :organization.

Fixes #6147 - filter both org and env in sys

systems index action does not filter by environment_id when both
organization_id and environment_id are passed; it only filters by
organization_id. This allows the index action to filter by both.

Fixes #6195, bz1109386 - 403 on cv version delete

Content view remove call specifying versions and envs to be removed / unasssociated
had a minor glitch -> env_ids - @view.environment_ids.map(&:to_s)).empty?
env_ids = [1,2,3]  while @view.environment_ids.map(&:to_s) = [1,2,3]
Problem was API was treating it like a list of strings while params code changed it to ints
This commit should fix that issue
