[SPARK-23122][PYTHON][SQL] Deprecate register* for UDFs in SQLContext and
Catalog in PySpark
## What changes were proposed in this pull request?
This PR proposes to deprecate `register*` for UDFs in `SQLContext` and
`Catalog` in Spark 2.3.0.
These are inconsistent with Scala / Java APIs and also these basically do
the same things with `spark.udf.register*`.
Also, this PR moves the logcis from `[sqlContext|spark.catalog].register*`
to `spark.udf.register*` and reuse the docstring.
## How was this patch tested?
Manually tested, manually checked the API documentation and tests added to
check if deprecated APIs call the aliases correctly.
