A new `DISTRIBUTED_COORDINATION_CONFIG` configuration provides a unified Redis-based backend for real-time coordination features in Superset. This backend enables:
- **Pub/sub messaging** for real-time event notifications between workers
- **Atomic distributed locking** using Redis SET NX EX (more performant than database-backed locks)
- **Event-based coordination** for background task management
The signal cache is used by the Global Task Framework (GTF) for abort notifications and task completion signaling, and will eventually replace `GLOBAL_ASYNC_QUERIES_CACHE_BACKEND` as the standard signaling backend. Configuring this is recommended for Redis enabled production deployments.

Example configuration in `superset_config.py`:
```python
SIGNAL_CACHE_CONFIG = {
DISTRIBUTED_COORDINATION_CONFIG = {
"CACHE_TYPE": "RedisCache",
"CACHE_KEY_PREFIX": "signal_",
"CACHE_REDIS_URL": "redis://localhost:6379/1",
