SQOOP-3123: Introduce escaping logic for column mapping parameters (same
what Sqoop already uses for the DB column names), thus special column
names (e.g. containing '#' character) and mappings realted to those
columns can be in the same format (thus not confusing the end users), and
also eliminates the related AVRO format clashing issues.
