The original purpose of the escapechartesttable was to test Impala's behavior on text tables that have the same character as line terminator and escape character. Recent changes in Hive have made creating such a table impossible because 1) Only newline is allowed as the line terminator 2) Newline is forbidden as the escape character See HIVE-11785 for details on the Hive changes. This commit removes escapechartesttable and all associated tests, but does not add the same enforcement rules as Hive. These enforcement rules should be added in a follow-on change.
