Description

Currently, in query process, no matter there is time filter in sql or not, PartitionFetcher will choose to fetch that from confignode through rpc instead of trying to use cache.

However, if query sql has timefilter like `where time >= XX and time <= XXX`, we may get data partition info in local cache.
