Please add auth option for external log drain requests. That way we can protect our log ingest endpoint by allowing only authorized agents.

Reference documentation here.

Proposed solution:

• Add an optional write-only auth field in the logs config form.
• If auth field not empty, add Authorization header with the value from auth field on requests to external log drain endpoint.

Example:

auth field contains value Basic YWRtaW46cGFzc3dvcmQ=, results in a header Authorization: Basic YWRtaW46cGFzc3dvcmQ=

This also allows for other types of auth, like Bearer and Api-Key tokens.
