…nd cache the consistent hash ring (apache#28522)

1. Use consistent hash algo as the default assigner for file query scan node
    A consistent assignment can better utilize the page cache of BE node.

2. Cache the consistent hash ring
    Init a consistent hash ring is time-consuming because there a thousands of virtual node need to be added.
    So cache it for better performance
