Description of problem:
-----------------------

Module streams are not working as expected in Red Hat Satellite 6.10.2-1. On a RHEL 8 content host registered to Red Hat Satellite 6.10.2-1, module streams that should be enabled by default aren't. User has to enable them manually on the content host. For example by running:
~~~ # yum module enable python36:3.6 ruby:2.5
~~~

Otherwise, errors like this one are encountered:
~<sub>~
Execution of '/usr/bin/dnf -d 0 -e 1 -y list python36' returned 1: Error: No matching Packages to list
[...]
change from 'purged' to 'present' failed: Execution of '/usr/bin/dnf -d 0 -e 1 -y install rubygem-foreman_scap_client' returned 1: Error:

How reproducible:
-----------------
Always with CVs that has a filter to include errata by date.

Actual results:
---------------
Module streams, that should be enabled by default on a RHEL 8 content host, are disabled and need to be enabled manually.

Expected results:
-----------------
Module streams, that should be enabled by default on a RHEL 8 content host, are enabled without the need for manual intervention.

Additional info:
-----------------
It appear that Satellite 6.9 has the copy :module_default units but I don't see any in Satellite 6.10 in "copy_content_for_source", "copy_units" and "additional_content_hrefs" methods

1. Satellite 6.9
   def copy_contents(destination_repo, filters: nil,
   solve_dependencies: false,
   rpm_filenames: [])
   ...
   [:srpm, :errata, :package_group, :package_environment,
   :yum_repo_metadata_file, :distribution, :module_default, :drpm].each do |type|
   tasks << smart_proxy.pulp_api.extensions.send(type).copy(repo.pulp_id, destination_repo.pulp_id)
   end

Katello uses "copy_content_for_source" (in Katello::Pulp3::Repository::Yum) to copy contents for Pulp3. This method will copy everything (rpm, errata, modules, package group, yum metadata etc) but missed modulemd defaults.
