Datasource is hardcoded for `v1beta1` api

[cbluth]

this is for grafana version: v6.6.1 (21bf8b71bc)

configuring a new kubernetes-api datasource always results in failures (404 errors)

the failing URL is this:
http://grafana.mydomain:3000/api/datasources/proxy/4/apis/apps/v1beta1/namespaces/kube-system/deployments

{"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"the server could not find the requested resource","reason":"NotFound","details":{},"code":404}

but, this URL works:
http://grafana.mydomain:3000/api/datasources/proxy/4/apis/apps/v1/namespaces/kube-system/deployments

[... lots of data ...]

Same here, this hardcoded value seems to impact dashboards as well by the fact that variables use the kubernetes-api datasource too. (Cannot get deployments status)

@GuillaumeOuint

i have made some simple edits, basically search/replace, and i can get past my issue as shown in the screenshot above^, see the branch here: master...cbluth:master

but, although this allows me passed the initial issue, the kubernetes app still has some major issues with querying data, and i dont know javascript well enough to troubleshoot.
