…tion during ingesting ### What problem does this PR solve? Issue Number: close #xxx Related PR: #xxx Problem Summary: In the previous PR #48467, a thread_local http connection is added to save the reconnect latency. However during the mixed workloads (both stream load and downloading binlog), the persistent connection will be blocked by the stream loading, which causes a latency spike. The ingest latency with a persistent connection:  The ingest latency without persistent connection:  This PR makes a persistent connection for each ingesting task, and adding a config `enable_ingest_binlog_with_persistent_connection` to control whether to use the persistent connection. The config is disabled by default, and users who need to download binlogs over long distances can enable it to reduce the sync latency. ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
