Resolution: Fixed
> Race condition on partition assigned to TopicBasedRemoteLogMetadataManager

> Issue Type: Sub-task

> TopicBasedRemoteLogMetadataManager (TBRLMM) uses a cache to be prepared
> whever partitions are assigned.
> When partitions are assigned to the TBRLMM instance, a consumer is started to
> keep the cache up to date.
> If the cache hasn't finalized to build, TBRLMM fails to return remote
> metadata about partitions that are store on the backing topic. TBRLMM may not
> recover from this failing state.
> A proposal to fix this issue would be wait after a partition is assigned for
> the consumer to catch up. A similar logic is used at the moment when TBRLMM
> writes to the topic, and uses send callback to wait for consumer to catch up.
> This logic can be reused whever a partition is assigned, so when TBRLMM is
> marked as initialized, cache is ready to serve requests.
