Increase apiserver wait time for a min

In openshift 4.7 looks like the moment we start the kubelet service
and kubelet being able to start the pod, have added more than a min
time. This patch will unblock us to start the 4.7.0-rc testing.

We should revert it as soon as https://bugzilla.redhat.com/show_bug.cgi?id=1927263
is fixed.
