* fix(threadpool): MCOL-5565 queries stuck in FairThreadScheduler. (#3100) Meta Primitive Jobs, .e.g ADD_JOINER, LAST_JOINER stuck in Fair scheduler without out-of-band scheduler. Add OOB scheduler back to remedy the issue. * fix(messageqcpp): MCOL-5636 same node communication crashes transmiting PP errors to EM b/c error messaging leveraged socket that was a nullptr. (#3106) * fix(threadpool): MCOL-5645 errenous threadpool Job ctor implictly sets socket shared_ptr to nullptr causing sigabrt when threadpool returns an error (#3125) --------- Co-authored-by: drrtuy <roman.nozdrin@mariadb.com>
