Pull Request Overview

This PR fixes the behavior of the sentinel command response in Redis by updating the execute_command function to correctly parse responses and returning either a boolean or the original response based on the provided options.

• Updates in both synchronous and asynchronous sentinel modules to pop "once" and "return_responses" from kwargs and return the processed response.
• Updates to the Redis commands for sentinel to pass the new execution options.
• An update to the CHANGES file documenting the fix.
