[DISCUSS] KIP-1341: Replace placeholder in ConfigEntity#name() with Optional entityName()

[Ming-Yen Chung]

Hi all,

I would like to start a discussion on KIP-1341: Replace <default>
placeholder in ConfigEntity#name() with Optional<String> entityName()
<https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=421958794>

ConfigEntity#name() returns "<default>" for default quota entities, while
every other public API uses null. The "<default>" value is a leftover from
the ZooKeeper era and has no meaning in KRaft. This KIP adds
Optional<String> entityName() and deprecates name().

Thanks,
Ming-Yen
