Hi community The Client API can create topic names of infinite length. But after these topics were created, we can not manage them by Admin API because the web service (based by Jetty) has a request-line length limit.
I propose adding a pulsar configuration `httpMaxRequestHeaderSize` to set this internal web service config (including web servicer and proxy service). I have submitted a PR to do this: https://github.com/apache/pulsar/pull/19514 Due to the previous bug of loop creation of DLQ(see https://lists.apache.org/thread/q1m23ckyy10wvtzy65v8bwqwnh7r0gc8), I think customers should need this configuration to remove these topics that shouldn't exist, so I think this change should be cherry-picked into branches 2.9, 2.10, and 2.11 Thanks Yubiao Feng
