congbobo184 opened a new pull request, #18074:
URL: https://github.com/apache/pulsar/pull/18074

   discuss: https://lists.apache.org/thread/0ts6josxxq4gt3qw2toxf9jd77d7s6kj
   ### Motivation
   Now, we have two authentications for updating the schema
   1. producer and consumer can update the schema using TopicOperation
   produce or consume when open autoUpdateSchema
   2. pulsar admin uses Tenant authentication
   
   This will produce problems when using different authentications to
   update the schema.
   ### Modification
   1. admin use produce permission to update the schema
   2. enable autoUpdataSchema, the client can use produce permission to update 
the schema automatically. When no schema in the topic, consume permission also 
can first update the schema automatically first
