[SPARK-12012][SQL] Show more comprehensive PhysicalRDD metadata when visualizing SQL query plan
This PR adds a `private[sql]` method `metadata` to `SparkPlan`, which can be used to describe detail information about a physical plan during visualization. Specifically, this PR uses this method to provide details of `PhysicalRDD`s translated from a data source relation. For example, a `ParquetRelation` converted from Hive metastore table `default.psrc` is now shown as the following screenshot:
And here is the screenshot for a regular `ParquetRelation` (not converted from Hive metastore table) loaded from a really long path:
