~~~
Create new cluster with 2 controller node (with isolated network)
after the cluster turn to active status, stop one of two controller nodes
Testing: get node of the cluster (using kubectl)

##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
Still can continue to access the cluster
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
Cannot access the cluster with result:
Error from server (Timeout): the server was unable to return a response in
the time allotted, but may still be pr
ocessing the request (get nodes)
Unable to connect to the server: EOF
~~~
~~~
I also created a cluster with three controller nodes and upon attempting to
stop two of them. I found that the result was consistent.
This means that the cluster can still be accessed with at least two
controller nodes while HA enabled?!
