Add run_concurrent_tasks utility function in tempest.common.concurrency to enable tempest plugins to write concurrency tests for parallel operations. The function handles multiprocessing, exception collection, and cleanup automatically. All tempest plugins (cinder, manila, glance, etc.) can consume this utility by passing their service-specific resource_count configuration. Changes: - Add run_concurrent_tasks helper function - Add unit tests for the new utility - Add release note Change-Id: I6071a30069aa0e83c079dec9da90e8ebb9f3b254 Signed-off-by: lkuchlan <lkuchlan@redhat.com>
