Create Helm Chart

[netflash]

To make it more convenient to run this bot inside the Kubernets cluster it would be nice to have a helm chart.

For those who doesn't familiar with what helm charts is - https://github.com/kubernetes/helm/blob/master/docs/charts.md

I already have my opinionated solution, which I gonna polish and pull-request somewhere next week.

Any ideas and/or thoughts are highly appreciated!

I have it. I use it. Not ready for merging yet. I can polish it a little bit today and create a PR for review.
