Fixes #9038 ### Motivation As described in [PIP-70](https://github.com/apache/pulsar/wiki/PIP-70%3A-Introduce-lightweight-broker-entry-metadata). One of the use case for Broker entry metadata is providing continuous message sequence-Id for messages in one topic-partition which is useful for Protocol Hanlder like KOP. This PR enable Pulsar to support continuous offset for message based on Broker entry metadata. ### Modifications Introduce a new field for broker entry metadta named `offset`; Introduce a new interceptor type `ManagedLedgerInterceptor` which intercept entry in `ManagedLedger`； Each partition will be assigned a `ManagedLedgerInterceptor` when `ManagedLedger` created; Each Entry will be intercept for adding a monotone increasing offset in Broker entry metadata and the offet is added by batchSize of entry; Support find a position by a given offset. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
