Suanming Mou Aug. 9, 2022, 1:25 p.m. UTC
In queue based async flow engine, in order to optimize the flow
insertion rate, PMD can use the hints from application to have
resources pre-allocate during initialization phase for actions
such as count/meter/aging.

This commit adds the connection tracking action hints.
