Use camelCase for properties instead of snake case.

We are discussing the following default, opening the issue not to forget it.

Docs says:

Similarly, Go field names will be converted from Pascal case to Snake case. For example, the struct field SomeField string will be accessible in JS as the some_field object property. This behavior is configurable with the js struct tag, so this can be changed with SomeField string js:"someField" or the field can be hidden with `js:"-"

To align with common JS convention, I suggest naming the property configMaps instead of config_maps:

• kubernetes.configMaps.get(name)
• kubernetes.configMaps.list()
