Cae 1130 timeout tests (redis#3377)

* initial WIP, with lots of debugging, and some non-working tests

* debug

* more attemtps at debugging

* Refactor: Move cluster state management methods from MaintenanceNotificationTest to RedisEnterpriseConfig

- Moved refreshClusterConfig, recordOriginalClusterState, and restoreOriginalClusterState methods
- Updated call sites in MaintenanceNotificationTest to use RedisEnterpriseConfig methods
- Added required imports and static variables to RedisEnterpriseConfig
- Maintained existing functionality while improving code organization

Improvements to RelaxedTimeoutConfigurationTest:
- Simplified traffic generation logic by removing complex multi-phase testing
- Streamlined BLPOP command execution with better timeout detection
- Added relaxed timeout detection and recording during maintenance events
- Improved logging and error handling for timeout analysis
- Enhanced test assertions to focus on relaxed timeout detection rather than success counts
- Added MOVING operation duration tracking for better test analysis

* Improve test reliability and cleanup: Add @AfterEach cleanup, enhance endpoint tracking, and improve logging

* add un-relaxed tests. will investigate further why they got broken at some point via diff

* CAE-1130: Update timeout configuration test and watchdog implementation

* Reset MaintenanceAwareConnectionWatchdog.java and log4j2-test.xml to upstream versions

* Clean up debug info and outdated comments from timeout tests

- Remove large debug block with reflection-based debugging in RelaxedTimeoutConfigurationTest
- Simplify excessive debug logging and verbose markers (*** and ===)
- Clean up maintenance notification test logging
- Improve push notification monitor message formatting
- Maintain all test functionality while improving code readability

* Refactor: Move inline comments above code and fix string comparisons

- Move all inline comments to be above the code they reference in:
  * RelaxedTimeoutConfigurationTest.java
  * RedisEnterpriseConfig.java
  * MaintenanceNotificationTest.java
- Replace string != comparisons with .equals() for proper string comparison
- Apply code formatting via Maven formatter

This improves code readability and follows Java best practices for string comparison.
