Issue reported privately by community user. In some scenario (user had semi-sync + long row data)
gh-ostconnections piled up toMAX_USER_CONNECTIONS. This PR puts a hard limit (constant3) on all pools. There's several of those (inspector, applier, throttler, and more), but each is limited to to 3 connections which at least does not cause a connection pileup on the MySQL server(s).script/cibuildreturns with no formatting errors, build errors or unit test errors.
