[SPARK-22214][SQL] Refactor the list hive partitions code
## What changes were proposed in this pull request?
In this PR we make a few changes to the list hive partitions code, to make
the code more extensible.
The following changes are made:
1. In `HiveClientImpl.getPartitions()`, call `client.getPartitions` instead
of `shim.getAllPartitions` when `spec` is empty;
2. In `HiveTableScanExec`, previously we always call
`listPartitionsByFilter` if the config `metastorePartitionPruning` is enabled,
but actually, we'd better call `listPartitions` if `partitionPruningPred` is
empty;
3. We should use sessionCatalog instead of SharedState.externalCatalog in
`HiveTableScanExec`.
## How was this patch tested?
Tested by existing test cases since this is code refactor, no regression or
behavior change is expected.
