Extend sdk to support additional operations

[cmoulliard]

Is it possible to extend operator-sdk/pkg/sdk in order to support by example such additional request able to create a subresource for a DeploymentConfig ?

https://goo.gl/uCxqWY

// Instantiate takes the representation of a deploymentRequest and creates it.  Returns the server's representation of the deploymentConfig, and an error, if there is any.
func (c *deploymentConfigs) Instantiate(deploymentConfigName string, deploymentRequest *v1.DeploymentRequest) (result *v1.DeploymentConfig, err error) {
	result = &v1.DeploymentConfig{}
	err = c.client.Post().
		Namespace(c.ns).
		Resource("deploymentconfigs").
		Name(deploymentConfigName).
		SubResource("instantiate").
		Body(deploymentRequest).
		Do().
		Into(result)
	return
}

We are moving closer to using the controller runtime and we will be using their client. You can find the documentation here https://godoc.org/sigs.k8s.io/controller-runtime/pkg/client#Client.

It appears that they also do not have support for subresources besides /status.

I am going to close this issue in favor of kubernetes-sigs/controller-runtime#172. We can re-open this feature request depending on the outcome of that issue.
