## Problem Summary

This merge request addresses issue !669 surrounding the behavior
of the "noop" authentication method, which underwent changes in commit
6f8ab4f. Reverting these changes to restore the previous behavior is
challenging due to the potential for breaking existing systems. To mitigate
this risk, we propose implementing a new authenticator named "delegate" to
replicate the original behavior of the "noop" method.

## Ideal Solution

To address this issue, our proposed solution is to implement a new
authenticator named "delegate" that replicates the original behavior of the
"noop" method. This approach ensures that existing systems in production
remain stable and unaffected by changes, while also providing users who
prefer the old behavior with an option to utilize it. By introducing the
"delegate" authenticator, we mitigate the risk of breaking changes while
offering flexibility to users who require the previous behavior.

## Changes Proposed

1. **New Authenticator Module**: This MR adds a new authenticator module
named "delegate" to replicate the original behavior of the "noop" method.

3. **Integration Tests**: Integration tests will be added to validate the
functionality of the "delegate" authenticator, ensuring compatibility and
reliability.

4. **Documentation Updates**: Documentation will be updated to include
details about the new "delegate" authenticator, its configuration options,
and usage examples.
