Review Comment:
This PR replicates the SparkCatalog behavior, which is fine by me.
> - If cache.expiration-interval-ms is zero, caching will be turned off
entirely (irrespective of the cache-enabled flag)
> - If users pass in a value <= -1, (with cache-enabled=true), then caching
will be enabled and cache expiration will never happen (i.e. entries will
persist unless explicitly refreshed, original behavior).
I find it a little weird that zero and negative numbers have different
implications. why distinguish those two? @kbendick can you share some context?
