Add helm chart

[cephasara]

Adds helm chart support for Kubernetes with minimal documentation.

What works:

1. Setting cpu/memory options
2. Setting VNC password
3. Persistance
4. Setting SMBIOS
5. QEMU/virtio cpu changes
6. Toggling Audio
7. Additional port forwarding
8. Kubernetes resource requests/limits
9. Defining install partition size

What doesn't/isn't defined:

1. Defining a different version of macOS
2. Additional QEMU parameters
3. GPU support

I have written this to leverage everything defined in the Dockerfiles, without making changes to them directly, but via Kubernetes configmaps instead. This makes it easier to merge into the existing codebase without breaking anything, albeit this is less optimized as it could be. For example, mac_hdd_ng.img is created twice [once in the Dockerfile itself and again with the Kubernetes configmap] as this allows us to update parameters and to maintain persistence.

I just want to share this in case anyone else would like to use this and contribute to it. It is by no means perfect--as it has been a hobbyist project for me, but a good starting point for anyone else whom might like to pick it up.

Thanks for this! I will take a look shortly!

Thank you so much for this!

Should I now register this at Helm? Or will you do the honors?

Edit: not sure how to, on mobile, will give it a whirl in a few hours
