* feat: Enhance Locust load testing for Langflow run endpoint
Refactor locustfile to provide more robust and configurable load testing:
- Add dynamic configuration via environment variables
- Improve error handling and logging
- Implement realistic flow run simulation
- Add connection and timeout handling
- Support API key authentication
- Enhance stats tracking and error reporting
* fix: Improve transaction logging error handling and performance
- Add `no_autoflush` context to prevent unnecessary database operations
- Change transaction logging error from exception to error level logging
- Simplify error handling in log_transaction function
* chore: Add Locust to development dependencies
Update project dependencies by adding Locust (version 2.32.9) to the development requirements, supporting load testing capabilities
* feat: Optimize database connection settings for improved performance and scalability
- Increase default pool_size from 10 to 20 for better connection handling
- Adjust max_overflow to 40 to support higher concurrent connections
- Extend db_connect_timeout from 20 to 30 seconds
- Add pool_recycle and echo settings to db_connection_settings
- Enhance documentation for database connection settings, highlighting SQLite limitations
* feat: Add Locust load testing configuration to Makefile
- Introduce comprehensive Locust load testing target with configurable parameters
- Support flexible testing scenarios with customizable users, spawn rate, and host
- Enable headless and interactive testing modes
- Add environment variable support for API key, flow ID, and other testing parameters
- Provide sensible default values for load testing configuration
* refactor: Remove unused retry configuration in Locust load testing
- Remove RETRY_DELAY and MAX_RETRIES environment variables
- Simplify FlowRunUser configuration by eliminating unused retry settings
- Maintain existing wait time configuration for load testing
* feat: Enforce FLOW_ID requirement for Locust load testing
- Add mandatory validation for FLOW_ID environment variable
- Raise a clear ValueError if FLOW_ID is not provided
- Remove default flow ID to ensure explicit configuration
- Improve load testing configuration robustness
* feat: Add configurable request timeout for Locust load testing
- Introduce `locust_request_timeout` parameter in Makefile
- Update locustfile to use configurable request timeout from environment variable
- Set dynamic connection and network timeout based on REQUEST_TIMEOUT
- Improve request handling with flexible timeout configuration
* revert change to database connection retry
