feat(backend): Make Redis connection Sync + Use Redis as Distributed Lock

[majdyz]

Background

Main issue:
We rely on the idea of rest_api being a singleton service to maintain our distributed lock. This will cause issues when the number of services increases.

Side issue:
The Redis operation that is used in our system has nothing to do with our API request:

• For read & write to queue done by a background process.
• (Added) To acquire a mutually exclusive lock.

Using Redis on asyncio will add unnecessary overhead and overscribe the event loop shared by Prisma queries.

Changes 🏗️

• Migrate distributed lock from rest_api to Redis.
• Switch Redis to synchronous client.
• Cleanup on connection retry logic on db.py and redis.py (newly introduced).
• Remove InMemoryEventQueue and make integration test use Redis queue.

Testing 🔍

Note

Only for the new autogpt platform, currently in autogpt_platform/

• Create from scratch and execute an agent with at least 3 blocks
• Import an agent from file upload, and confirm it executes correctly
• Upload agent to marketplace
• Import an agent from marketplace and confirm it executes correctly
• Edit an agent from monitor, and confirm it executes correctly

🧪 No relevant tests

🔒 Security concerns Sensitive information exposure: The PR introduces Redis connection details in autogpt_platform/backend/backend/data/redis.py. While environment variables are used, there's a risk of exposing default values (e.g., "password" for Redis password) if the environment variables are not properly set.

⚡ Key issues to review Error Handling The connect() and disconnect() functions use logged_retry without proper error handling or maximum retry limit. Error Handling The RedisEventQueue methods lack proper error handling for Redis connection issues. Potential Deadlock The synchronized context manager acquires a lock but doesn't handle potential exceptions, which could lead to a lock not being released.
