The "new version of minikube" message shouldn't have the type io.k8s.sigs.minikube.error

[jtzwu]

Steps to reproduce the issue:

1. Run minikube start --output=json

Full output of minikube start command used, if not already included:
...
{'data': {'message': 'minikube 1.12.3 is available! Download it: https://github.com/kubernetes/minikube/releases/tag/v1.12.3\n'}, 'datacontenttype': 'application/json', 'id': '561b5628-0fac-487d-b5fd-028a4c63503a', 'source': 'https://minikube.sigs.k8s.io/', 'specversion': '1.0', 'type': 'io.k8s.sigs.minikube.error'}

@tstromberg just wanted to confirm even the below one type shouldn't be io.k8s.sigs.minikube.error correct ?

{"data":{"message":"/home/vinu/go_workspace/bin/kubectl is version 1.20.0-alpha.0.188+65a1f24b205ece-dirty, which may be incompatible with Kubernetes 1.18.3.\n"},"datacontenttype":"application/json","id":"f6ee3909-ef29-4667-8f46-951427b4314a","source":"https://minikube.sigs.k8s.io/","specversion":"1.0","type":"io.k8s.sigs.minikube.warning"}

{"data":{"message":"You can also use 'minikube kubectl -- get pods' to invoke a matching version\n"},"datacontenttype":"application/json","id":"51d20524-d797-4f98-a452-0d2e6a84fb33","source":"https://minikube.sigs.k8s.io/","specversion":"1.0","type":"io.k8s.sigs.minikube.error"}

I might be wrong. Please ignore if i am wrong here.
The above messages are seen when the Kubectl clientMajor version != Cluster Major version OR the minor version of both is greater than 1.

@vinu2003 - Your right, that does not sound like an error either. Do you mind sending a PR for it?

[vinu2003]

Sure I will send it @tstromberg. Thank you.
