[release-4.18] OCPBUGS-76963: Extends the time for the extractor liveness probe

[jmesnil]

• Backporting

Before:

• crictl info was timing out after 2 seconds
• the command was executed every 10 seconds
• 2 failures were making the container unhealthy
• => 10 seconds of unavailability was making the pod crash

This was too constraining as there are occasions where crictl can be unavailable for a longer period of time (eg when the TLS CA bundle requires to restart some pods)

Now:

• crictl info is timing out after 10 seconds
• the command is executed every 30 seconds
• 3 failures (default) are making the container unhealthy
• => 1m30s of unaivailability is making the pod crash

Note: The liveness probe is used instead of the readiness probe as the container MUST crash if the crictl connection has been changed (eg following a TLS CA bundle update) and at this point, the pod must be recreated to be able to connect to cri-o socket with an updated TLS certificate.

This fixes https://issues.redhat.com/browse/OCPBUGS-76963
Upstream issue is https://issues.redhat.com/browse/OCPBUGS-66996
