Fix: Issues with cooperative-sticky strategy

[golanbz]

Description

• Added support for consumer strategies that do not require "stop the world" scenarios (e.g., cooperative sticky). This addresses and fixes issues #557 and #456.
• Enabled automatic committing with confluent.auto.commit: true for the cooperative sticky consumer strategy, instead of relying solely on manual commits. This change is particularly relevant due to the ongoing issue in librdkafka (see: https://github.com/confluentinc/librdkafka/issues/4059).

How Has This Been Tested?

• Introduced a new sample project specifically designed to evaluate and test the support for the cooperative sticky strategy, allowing for more thorough analysis.
• Unit tests were added for the updated classes to address the new behavior.
