@sboeuf this release is not big, I think we can wait for kata-containers/runtime#131, let us know to wait the merge for 3.0.23 release.

[sboeuf]

@jcvenegas Once kata-containers/runtime#131 gets merged, I'll revendor the CC runtime and we'll include this into the release.

[sboeuf]

The metrics CI fails because it could not run some network tests, due to the iperf server being down for some reasons.
But this PR is a simple tag release, there is no reason to block it for such a reason. I'll merge it !
