Automatic merge from submit-queue (batch tested with PRs 41980, 42192, 42223, 41822, 42048) Adjust parameters of GCL cluster logging load tests This PR increases the amount of logs produced in load tests to match the number of nodes and provide the predictable load of 100 KB/sec on each node. Also this PR reduces in half amount of time, given for ingesting logs.
