Setting cluster status to active without passing --environment does not return error

[swarupdonepudi]

When I ran the command to set cluster status to active without passing the environment, the call returns a "Setting cluster status active" message but does not really set the cluster to active. But when I pass --environment dev I see the following output.

Setting cluster environment to dev
Setting cluster status active

Does not work(which is great): kubectl hyperkube set-cluster-status --status active --cluster <cluster-fqdn> Works: kubectl hyperkube set-cluster-status --status active --cluster <cluster-fqdn> --environment <cluster-env>

Not working version should display an error message to the user.
