[SPARK-10380][SQL] Fix confusing documentation examples for
astype/drop_duplicates.
## What changes were proposed in this pull request?
We have seen users getting confused by the documentation for astype and
drop_duplicates, because the examples in them do not use these functions (but
do uses their aliases). This patch simply removes all examples for these
functions, and say that they are aliases.
## How was this patch tested?
Existing PySpark unit tests.
