Support HTTPS certificates

[sevensolutions]

At the moment you can define an https-binding, but theres no way to specify a certificate.

TODOs:

• Implement install/uninstall from a local file
• Make sure we don't break IIS because of invalid certificates
  • https://learn.microsoft.com/de-de/archive/blogs/kaushal/error-hresult-0x80070520-when-adding-ssl-binding-in-iis
• Document where to find the installed certificates
• Write Integration Tests
• Rename certificate_hash to certificate_thumbprint
  • Or maybe even change this to an certificate-object

We're now supporting HTTPS certificates by specifying the certificate hash. This requires the certificate to be already installed on the machine.

We should add another way to install a certificate, downloaded via an artifact and also remove it, if there's no website referencing it anymore.

As a hint: https://learn.microsoft.com/en-us/iis/get-started/whats-new-in-iis-8/iis-80-centralized-ssl-certificate-support-ssl-scalability-and-manageability

We should at least add a flag to use certificates from the centralized certificate store.

Maybe I'll also add auto install support for certificates from vault.

I will not support that because with the new file support, one can simply use vault and a template stanza.
