Add support for authenticating with API Keys

[mcohen75]

The Confluent Cloud API supports authenticating with API keys. API Keys provide some nice advantages for certain use cases, such as infrastructure as code tools like Terraform.

Support for API keys uses basic authentication, where the API Key is the username and the secret is the password.

See:
https://confluent.cloud/api/docs#section/Authentication

Note that "Cloud API Keys" provide access to the Confluent Cloud Control Plane APIs.

I'm affraid that the current Confluent Api does not support authenticating using an Api key. And the v2 of the Api is in early access stage, and does not include Api keys and Acls management...

Looks like we're stuck...

@mcohen75 @arkiaconsulting Hello, I'm also looking for api-key/secret authentication, seems like confluent api v2 now does supports api-key/secret auth. 🙂
