Revert "RHCOS: update to release 42.80.20190823.0"

[stbenjam]

This reverts commit 067c05a. This
version of RHCOS is shipping with a broken podman that does not
correctly return exit codes. The fix from
https://bugzilla.redhat.com/show_bug.cgi?id=1741157 needs to be
backported into a new podman RPM for EL8 and the fix brought into RHCOS.

If the etcd health check fails, bootkube continues on regardless instead
of retrying. This manifests itself most catastrophically for the
baremetal IPI platform, where the first etcd health check fails very
quickly as DNS records aren't available yet.

Hmm but that's going to back out other important fixes...

[stbenjam]

We could also ask for a new RHCOS build with an older podman without this problem

[stbenjam]

baremetal IPI is most obviously hit by this, but having a broken podman like this is pretty catastrophic and is probably going to manifest itself in other odd ways. We should get a newer podman soon, but it would be a few days, and it's a long time to be in this situation.

[miabbott]

Older podman from the 42.80.20190725.1 build would be podman-1.4.2-1.module+el8.1.0+3423+f0eda5e0

[abhinavdahiya]

I'm more inclined towards not backing out important fixes for our GA platforms like Azure, vSphere.

[stbenjam]

We may get a new RHCOS relatively quickly, backport PR is open containers/podman#3895

[yuqi-zhang]

We're working on both getting the new one, as well as a build for reverting ONLY podman to the old version for RHCOS. I think this can be closed in favour of either one.
