Case-insensitive handling doesn't work for types with multiple capital letters

[lblackstone]

#21 works for things like Deployment or Pod that only include one capital letter, but not for types like StatefulSet or DaemonSet with more than one capital letter.

Here's an example:

$ kubespy status apps/v1 statefulset foo
Server is unable to handle apps/v1, Kind=Statefulset

$ kubespy status apps/v1 StatefulSet foo
Watching status of apps/v1 StatefulSet foo
