> - There are some problem (such as IPV6 based cluster support) on okhttpclient 
> v3, but it's a little bit diffcult to upgrade to v4 [1]
> - Kubernetes client are also consider to support other clients [2] rather 
> than single okhttpclient.
> - Kubernetes client add a abstract layer [3] to address supporting 
> httpclient, okhttp client as one of supported http clients.
>  
> So, we better to consider to cleanup okhttpclient direct usage and use the 
> httpclient which kubernetes client diret supported to reduce the potential 
> risk in future upgrade.
