[SPARK-19148][SQL] do not expose the external table concept in Catalog
## What changes were proposed in this pull request?
In https://github.com/apache/spark/pull/16296 , we reached a consensus that
we should hide the external/managed table concept to users and only expose
custom table path.
This PR renames `Catalog.createExternalTable` to `createTable`(still keep
the old versions for backward compatibility), and only set the table type to
EXTERNAL if `path` is specified in options.
## How was this patch tested?
new tests in `CatalogSuite`
