[PR] HDDS-15660. Skip prometheus container during stack collection [ozone]

["chihsuan (via GitHub)" <gi...@apache.org>]

chihsuan opened a new pull request, #10631:
URL: https://github.com/apache/ozone/pull/10631

   ## What changes were proposed in this pull request?
   
   Test-only change.
   
   **Problem.** On acceptance test failure, `create_stack_dumps()` iterates over the service containers and runs `jstack` in each one. The container filter `grep -e datanode -e om -e recon -e s3g -e scm` matches by substring, so `prometheus` (pr**om**etheus) is accidentally selected. The `prometheus` image has no `bash`, so the stack dump step fails with:
   
   ```
   exec: "bash": executable file not found in $PATH
   ```
   
   producing noise and a useless `.stack` file in the result directory.
   
   **Fix.** Exclude the `prometheus` container from the stack collection loop by appending `grep -v -e prometheus` to the filter. Java service containers (including HA `om1/om2/om3`, `scm1/scm2/scm3`) are still selected.
   
   ## What is the link to the Apache JIRA
   
   https://issues.apache.org/jira/browse/HDDS-15660
   
   ## How was this patch tested?
   
   - Verified the updated filter still matches `ozone-om1-1`, `ozone-scm2-1`, `ozone-recon-1` and no longer matches `ozone-prometheus-1` / `ozone-grafana-1`.
