Add support for Microsoft Azure Key vault

We will work on adding that documentation, that seems valuable to have available for new contributors.

Adding a new backend would look like:

• Adding the fields to the SecretStore spec (AWS as an example)
• Implementing the StoreFactory interface to allow creation of the SecretStore backend and the StoreClient interface for fetching ExternalSecrets (interfaces)
• Registering the Store when an SecretStore resource is using the backend (registration)

This is still a pretty new project and we are still in-progress on docs and the initial functionality (#55 as an example).

Morning @ahmedmusAmadeus We dont have any timelines, and are getting to things when we have a moment to breathe from regular work stuff haha. If you want to contribute you are more than welcome to! We will go over any concerns in the MR

Thanks @dirtycajunrice for your response , it's totally understandable . Yes I am very enthusiastic to contribute and use your operator with Azure KV.
However can we have at least some sort of contribution guide how to inject a new Backend into the project . something like what's described here.
I think this documentation enhancement will help a lot of contributors to add different backends (not only Azure KV).

Hello, we have implemented the Azure KeyVault back-end for this operator. Only tests are still missing, but we have plan to make them in the coming weeks. However, given this answer #83 (comment) it looks like we may rather use our time to contribute our implementation to the new merged https://github.com/external-secrets/external-secrets.

What do you think? Where should we spend our energy?

@snowfix-1a I would recommend contributing the Azure KeyVault backend to https://github.com/external-secrets/external-secrets, the backend interfaces between this project and external-secrets is identical.
