GuoHao updated HDDS-10869:
--------------------------
Description:
SCMNodeManager#getUsageInfo this method will obtain the number of containers
for the node, create a container ID set, calculate the size of this set, and
create a large temporary object.
When there are too many containers in a node, this is a very time-consuming
operation:

Most of the operation time is consumed in this part:
