Add a license

[s4ke]

Hey @olljanat ,

could you add a (hopefully) permissive license to this repo, so we can take the example code you already worked on to build out the PRs in the other repos? This will make contributing much easier :)

Thanks!

Asking because I am working on a PR for Hetzner here: hetznercloud/csi-driver#376 and would very much would draw inspiration from your work.

There is MIT license already.

Ah, sorry. I overlooked this one. Thanks.
