[SPARK-15895][SQL] Filters out metadata files while doing partition
discovery
## What changes were proposed in this pull request?
Take the following directory layout as an example:
```
dir/
`- p0=0/
|-_metadata
`- p1=0/
|-part-00001.parquet
|-part-00002.parquet
|-...
...
```
The `_metadata` file under `p0=0` shouldn't fail partition discovery.
This PR filters output all metadata files whose names start with `_` while
doing partition discovery.
## How was this patch tested?
New unit test added in `ParquetPartitionDiscoverySuite`.
