HA: inject public certificates without blocking container

Do not inject public certificates in pacemaker bundles by means
of "podman cp", as this pauses the container for a short amount
of time and can make pacemaker operation fail during that time
window and impact cluster for no reason.

Keep "podman cp" for non-HA containers, as the freeze is short
and doesn't seem to impact podman monitoring anyway.

The new certificate injection only works for podman 1.9+, lower
version won't overwrite the existing certificate.

(cherry-picked from 93e53b7429)
(squashed with Ic6e4264c5ad46bd2589cc907c365af2d42fde63d)
(removed a part that should stay in puppet-tripleo before wallaby)
