verbose log output

Description of problem:

on ARO/Azure we see huge number of panic in the logs coming from etcd-proxy container. These are stale logs being printed again and again into log output. 
Which is confusing and should be fixed as it create false positive results in other issue debugging.


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

4.3++

in 1 day we have around 4000 of same panic message printed in the logs: 

[root@aro-master-0 ~]# cat 1_day.log | grep " http: panic serving 10.11.40.6:4143" | wc -l
3991
