Uses NSG with #139, bastion VM could be an alternative instead of default, closing this

What's the preferred resolution to this issue? Implementing a bastion (which I assume would be open to the internet?) or locking down the control plane NSG further? Seems a little difficult without user input to determine e.g. the desired ranges.

[alexeldeib]

Seems like this is going towards bastion VM, just saw #175

So I think what we need to do here is:

1. Change the default NSG rules so they are more restrictive, we don't want the NSG to ever be open to the whole internet
2. Look into Azure Bastion and maybe implement it as an optional feature.
