change Metadata's get method to return Option types
Class org.apache.spark.sql.catalyst.util.Metadata's get methods may throw
NoSuchElement exception if the key does not exist, and there is no method for
testing the existence of a key.
This PR changes the get methods to return Option types, as the convention
in Map.get.
