Mike Fedosin 8a81089785 Optimize mistral queries for 'get_task_executions' 
During workflow executions there are a lot of calls of function
'find_task_executions_by_name' from lookup_utils. This function
internally calls 'get_task_executions' with two filters: name and
workflow_execution_id.

To optimize this call it's reasonable to add a composite db index
by these two fields.

Another optimization is to explicitely disable sorting by 'created_at',
because it's unnecessary in this particulat case.
