 Starting from 4.0 release, we do not support directly calling exec or attach calls. you should use stream module to call them. so instead
 of `resp = api.connect_get_namespaced_pod_exec(name, ...` you should call `resp = stream(api.connect_get_namespaced_pod_exec, name, ...`.
 See more at [exec example](examples/exec.py).

+    Using Stream will overwrite the requests protocol in _core_v1_api.CoreV1Api()_ 
+    This will cause a failure in  non-exec/attach calls. If you reuse your api client object, you will need to 
+    recreate it between api calls that use _stream_ and other api calls.
