Allow custom subclasses of APIObject for Selector.object() and Selector.objects()

[pehala]

Overview

It would be great if Selector.objects() and Selector.object() would allow to specifiy which class it should create. This can be useful when you have custom class on top of APIObject for helping with managing said resource.

Example

oc.selector("pods").objects(class=DeploymentConfig) ~> List[DeploymentConfig]
oc.selector("pods").object(class=DeploymentConfig) ~> DeploymentConfig
oc.selector("pods").object() ~> APIObject

I think I could implement this if you would like this to be added.

@pehala Can you take a look at #83 and see if this meets your expectations?

@pehala I have merged the changes. They are available directly or from PyPI: https://pypi.org/project/openshift-client/1.0.9/
