[I] Persistence model built around implementation details [polaris]

snazy opened a new issue, #775:
URL: https://github.com/apache/polaris/issues/775

   ### Describe the bug
   
   The persistence model (as in `org.apache.polaris.core.entity`) is built around assumptions for a particular implementation. It does not just define different entity types (think: catalog, namespace, table, etc) but also implementation details about cache and data consistency details. These details leak though the whole code base that has to deal with any kind of entity. This makes it extremely difficult to use another persistence backend than the one this persistence model was built for, like the "simpler KV store" mentioned in `PolarisMetaStoreSession`.

   I disagree, because this effectively prevents the intention of the abstraction to have _pluggable_ storage even for "simpler KV stores", as defined in the Polaris-internal API.
