Some suggestions for improvements to auto-generated docs

[calebAtIspot]

I noticed a few minor improvements that can be made to the auto-generated docs. Admittedly, these changes are obvious for the user to make, but typically one expects examples to work out-of-the-box as much as possible.

• The empty classes don't always work. For example, pass in a empty kubernetes.client.V1ServiceAccount() to replace_namespaced_service_account and you'll get an error the name of the object (name-example based on URL) was undeterminable: name must be provided. The class could use arguments or a message telling the user to provide arguments.
• name does not follow kubernetes naming format, should have - instead of _
• namespace does not follow kubernetes naming format, should have - instead of _
