    Description

      Description of problem:

      Etcd's liveliness probe should be removed. 

      Version-Release number of selected component (if applicable):

      4.11

      Additional info:

      When the Master Hosts hit CPU load this can cause a cascading restart loop for etcd and kube-api due to the etcd liveliness probes failing. Due to this loop load on the masters stays high because the api and controllers restarting over and over again..  
      
      There is no reason for etcd to have a liveliness probe, we removed this probe in 3.11 due issues like this.
