Description

If a cluster enable user scan snapshot feature, it will work for all tables. Since this feature will make some operations such as grant, revoke, snapshot... slower and some tables don't use scan snaphot to make scan faster. So add a table attribute to make it configurable at table level, in general, the feature is disabled by default, and if someone use feature, must enable the attribute of the specific table firstly.
