[Systemroles] CI: ansible-2.9 tests are not good

[Richard Megginson]

I recently upgraded to the latest rhel7 container image.  There was a
problem with CA certs.  I reverted to the previous image.  Now ansible is
giving me the following error:

A worker was found in a dead state

I've tried several suggestions found online (env no_proxy="*", etc.) -
nothing helps.  Using ansible -vvvvvvvvv - no further information.  Using
ANSIBLE_DEBUG=true - no help.  Using ANSIBLE_FORKS=1 - no help.  The
machine has plenty of RAM.  I can reproduce locally using podman.  Not sure
what is going on.  So just ignore the ansible-2.9 CI results until further
notice.
