feat(example): python hello example

[campionfellin]

First pass at converting more-or-less the python into

to an actual example, that will be built by lerna with yarn build. We can use this to verify changes continue to work with python. It's also a great point of reference for python developers using cdk8s

@eladb this feels a bit odd, with package.json in it. Is there a different/better way to get lerna to build this?

You need package.json and that's fine. The problem is that this is going to be built against the published version of the CDK and not against the local build. To do that you'll need this to actually run after package, and you'll have to install the python module from dist/python instead of from PyPI.

Not 100% sure what's the best way to do that TBH.

@eladb I looked into it, and it seems I just needed the dependency on the cdk8s-cli, which is supplied by node_modules/.bin/cdk8s (which is in-place after a yarn install from lerna at the root of the repository).

I think folks can take the example and edit as-needed (remove package.json, add deps to Pipefile, etc), but this stands as a base starting point for users.

@eladb let's merge this and the other python examples
