Good catch @guohao-rosicky. Approving this, but it'll be good if we can incorporate the suggestion made by @adoroszlai.

(apache#7826) (cherry picked from commit 371792f) --------- Conflicts: 1. Forced to include CDPD-65217 (minor commit that only changes a method name) and CDPD-52140 to resolve conflicts. No major changes made. 2. Had to change a test method to use the full Assertions.assertEquals instead of just assertEquals. 3. CDPD-70111 - had to merge manually to exclude changes from other unrelated commits in ContainerBalancerTask. --------- Co-authored-by: Siddhant Sangwan <[email protected]> Co-authored-by: Symious <[email protected]> Co-authored-by: Tejaskriya <[email protected]> Co-authored-by: hao guo <[email protected]>

What changes were proposed in this pull request?
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.
