Description of change

Fixes #3139

• Made change to execute_command function to parse sentinel command response correctly and return the actual responses when new argument return_responses is set to True.
• This behaviour is exposed for several sentinel commands - sentinel_get_master_addr_by_name, sentinel_master, sentinel_sentinels
• The default behaviour is preserved, so this won't be a breaking change.

Hello,
@vladvildanov @gerzse , Can anyone look in to this PR ?

[vladvildanov]

@mahigupta Looks fine 👌 Working on fixing CI, docker-compose was removed from default commands in Ubuntu 22.04 LTS runner

@vladvildanov @gerzse Ci fixed now to go ahead with this PR ?

[petyaslavova]

This change will still need a few new unit tests to be added.

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.

Pull Request Overview

This PR fixes how sentinel commands parse and return responses by introducing a return_responses flag and removing the default True return behavior. It also updates several sentinel command wrappers to leverage this new flag and expands test coverage with real-sentinel integration tests.

• Enhance execute_command (sync/async) to pop once/return_responses flags and return a list or boolean accordingly
• Update sentinel command methods to use once=True and/or return_responses=True where appropriate
• Add deployed_sentinel fixtures and real-instance tests in both sync and asyncio suites

redis/commands/sentinel.py:15

• The method now returns a list of tuples (due to return_responses=True) rather than a single tuple; please update this docstring to reflect the new return type.

        """Returns a (host, port) pair for the given ``service_name``"""

redis/commands/sentinel.py:23

• This change makes sentinel_master return a list of dicts instead of a single dict, which is a breaking API change; consider documenting this behavior clearly or offering a non-breaking alternative.
