Description
Today we only have two places to store configs: server configs which is used to store server side global configs, and log configs to store others. However, many topic / partition level configs would be better stored in a partition config such that they do not need to require accessing the underlying logs, for example:
1. uncleanLeaderElectionEnable
2. minInSyncReplicas
3. compact [? this is defined per-topic / partition but maybe ok to store as log configs]
