[CORE] Windows support

Associated Template/Command/Core General Windows support for cookietemple

This issue serves as a list of all bugs that we need to fix to support Windows:

• cryptography is a pain to include into our CI pipelines due to cryptography. build\temp.win-amd64-3.8\Release\_openssl.c(546): fatal error C1083: Cannot open include file: 'openssl/opensslv.h': No such file or directory This is how cryptography builds it: https://github.com/pyca/cryptography/blob/master/.github/workflows/ci.yml A pain to set up

• Verify whether ‘git’ is always accessible as a subprocess.

• Windows has no ~/.config per default for Cookietemple config and key files

• Makefiles need to be made compatible with Windows. One possibility would be to write 2 Makefiles (Unix & Windows) and load the correct one depending on the OS

It may actually work to install OpenSSL using choco on windows: https://chocolatey.org/packages/openssl

Additional Issue: Makefile needs Windows support Unix commands from Unix are not supported by Windows rm -fr == rd /s /q
