[SPARK-23488][python] Add missing catalog methods to python API
## What changes were proposed in this pull request?
As noted in SPARK-23488, the Python Catalog API was missing some methods
that are present in the Scala API. Both for the sake of consistency, and
because of their utility, I've added the missing methods (the
database/table/functionExists() and getDatabase/Table/Function() methods).
I modeled these methods off of how the existing ones were written in
catalog.py.
## How was this patch tested?
manually tested the added methods and compared functionality to the scala
API counterparts
## Questions
I wasn't sure whether to set the `@since(x.y)` decorators on the new
functions, and if so, what value to set them to?
