[SPARK-21584][SQL][SparkR] Update R method for summary to call new
implementation
## What changes were proposed in this pull request?
SPARK-21100 introduced a new `summary` method to the Scala/Java Dataset API
that included expanded statistics (vs `describe`) and control over which
statistics to compute. Currently in the R API `summary` acts as an alias for
`describe`. This patch updates the R API to call the new `summary` method in
the JVM that includes additional statistics and ability to select which to
compute.
This does not break the current interface as the present `summary` method
does not take additional arguments like `describe` and the output was never
meant to be used programmatically.
## How was this patch tested?
Modified and additional unit tests.
