Add support for custom runtime image

[andresmgot]

Yes, that will do the job. Just one minor detail: the new parameter should be either set as service.provider.image or as service.functions.<function_id>.image that way you can have in the same serverless.yaml functions with a custom image and others with the official images.

If you feel like giving it a try I am happy to help if you get stuck in any step.

@andresmgot Thanks for the tips.
I've added the implementation and tests as you said, and works well in my test cluster.
Please let me know if anything else.

@ccll we would love to know what you are doing with kubeless, maybe we can relay a blog of yours. In any case, thanks for the great contributions

@sebgoa I'm trying to re-write my private web/data scraping service to work on kubernetes, I think k8s + serverless is very suitable for this kind of jobs. After evaluated several serverless frameworks, kubeless is the most mature and promising to me.

The whole thing is still in evaluation anyway, so far the experience is very good, despite some of the features do not work well enough. Do you folks have a rough schedule or roadmap on when will kubeless be production ready?
