Fixes #28082 - allow listing packages in safemode

[ares]

This is all that is needed for naive host diff report implementation such as

<%#
name: Content host diff
snippet: false
template_inputs:
- name: Host 1
  required: false
  input_type: user
  description: FQDN of the first host to compare
  advanced: false
  value_type: plain
  resource_type: AnsibleRole
- name: Host 2
  required: false
  input_type: user
  description: FQDN of the second host to compare
  advanced: false
  value_type: plain
  resource_type: AnsibleRole
model: ReportTemplate
%>
<%- host1 = Host.find_by_name(input("Host 1")) -%>
<%- host2 = Host.find_by_name(input("Host 2")) -%>
<%- set1 = host1.installed_packages.group_by { |p| p.name } -%>
<%- set2 = host2.installed_packages.group_by { |p| p.name } -%>
<%- (set1.keys | set2.keys).uniq.each do |package_name| -%>
<%-   data = { 'Package' => package_name } -%>
<%-   data[host1.fqdn] = set1[package_name].try(:first).try(:nvra) || '-' -%>
<%-   data[host2.fqdn] = set2[package_name].try(:first).try(:nvra) || '-' -%>
<%-   report_row data -%>
<%- end -%>
<%= report_render -%>

of course the report template needs a bit more enhancements to be fully useful, but this can be used for testing

Thanks @ares !! Seems very useful !

ignore test failures for now, i'm not exactly sure why a change in the pulp gems affected master tests but it seems to have now, this will be fixed today
