[fix][broker]Update interceptor handler exception

[tuteng]

Fixes #xyz

Master Issue: #xyz

Motivation

The pulsar-admin client does not correctly handle error messages from the interceptor response. The interceptor response is a string, but the client tries to parse it as an errorData object

https://github.com/apache/pulsar/blob/master/pulsar-client-admin/src/main/java/org/apache/pulsar/client/admin/internal/BaseResource.java#L323

Modifications

Update the response to a json object, update the response to a json object, which shouldn't cause a breaking change. The client will get the error message from the previous reason-content to "{"reason": "reason-content"}"
