FIX Floating-point calculation in provision.sh

[AlpacaMax]

Line 24 in k8s/debug/provision.sh will not work in bash as bash does not support floating-point calculations. I changed that line and now the calculation is done using bc.

What platform are you on where you spotted this issue? I haven't seen this come up on archlinux, MacOS and WSL.

[AlpacaMax]

It comes up on Ubuntu with bash version 5.0

[wabscale]

Ubuntu 18.04 or 20.04? Im just going to give this a try on different platforms before merging.

[AlpacaMax]

Pretty sure it's 20.04

Hmm ok, I'm seeing it calculate 15.50000000000000000000Gi on a 32 GiB system. I mean it is taking that number, but I don't think that is what we want. What are the memory resources on the machine you saw an issue on @AlpacaMax ?

[AlpacaMax]

So I saw this issue on a virtual machine with 4GB memory (it shows 3.8GiB in free -h). As a result it will try to compute 3.8 / 2, which gives me an error. After changing it to the version I wrote the calculation succeeded. Then minikube tells me my machine doesn't have enough resource for itself to run.

[wabscale]

Yeah unfortunately minikube debugging requires quite a bit of resources to work. Sometime soon we may be creating a debug cluster that we can get you access to. We'll still merge once I can confirm it works on all the main things.
