Provide fluent nested builders for model objects.

[iocanel]

Currently, the generated model has a builder-like structure baked inside the model objects.
Given the depth of the model, it would really help if the builders supported more advanced features like nesting, visitors and in-lining (similar to what we have in the https://github.com/fabric8io/kubernetes-client).

nesting makes it so much easier to create model objects directly in java. It's faster to write, it's more IDE friendly etc.

visitors allow making changes, without having to explicitly traverse the object tree. (e.g. allows doing things like visit all Pod Specs in the tree and add a sidecar container without having to care if the spec is under a Deployment, DeploymentConfig, Pod, ReplicaSet etc).

in-lining allows to use the builder structure but instead of building the object directly to pass the object to a function. This allows to seamlessly integrate the builder into the client dsl.

Now, if we could get those builders either as part of the kubernetes module, it would open up the room of aligning with the https://github.com/fabric8io/kubernetes-client.

Feel free to start writing them :) io.kubernetes.client.fluent or somesuch...

We could also generate them, I suppose, but someone needs to write the generator...

[brendandburns]

(another option is to use protocol buffers and the proto-client which are somewhat more fluent, in some ways)

[iocanel]

@brendanburns: I've written a generator myself that we used for the fabric8 kubernetes-client.
So let'me try to integrate it and see how it goes.

@iocanel did you make any progress?

@iocanel cool, would love to see it!

[saturnism]

would love to see this merged! i enjoy the fabric8 client a lot :)

[rhuss]

@iocanel I know, it has been some time and you are probably still very busy. But is there any chance for this PR still to happen ? 'would be really happy to help out here, too, as I think it would be a super awesome addition. We need something like this for the fabric8-maven-plugin to switch and would love to switch to kubernetes-client.

This was fixed with #323 and #357 has an example.
