Follow-up to apache#11509, that simply refactors the interface that we use when resolving a pluggable `DataSource`. - Multiple functions share the same set of arguments so we make this a case class, called `DataSource`. Actual resolution is now done by calling a function on this class. - Instead of having multiple methods named `apply` (some of which do writing some of which do reading) we now explicitly have `resolveRelation()` and `write(mode, df)`. - Get rid of `Array[String]` since this is an internal API and was forcing us to awkwardly call `toArray` in a bunch of places. Author: Michael Armbrust <michael@databricks.com> Closes apache#11572 from marmbrus/dataSourceResolution.
