Out-of-Order Execution

ALS is able to execute some requests out of order they are arriving. For these request we have several execution strategies:

• 🙅 (fence priority) - don't execute the request till any previously arrived requests are executed. This priority mostly works as in-order execution.
• 🐇 (high priority) - execute the request as fast as possible
• 🐢 (low priority) - execute the request in the background
