Generate avro schema from column name and type information. typeInfo in 1st parameter
needs to contain precision and scale information in the value(HiveTypeInfo).
The 2nd parameter qualifiedName will be the name of Avro Schema.
@param typeInfo  Record structure
@param qualifiedName qualified name that will be the name of generated avro schema
@return String avro schema
@throws HiveStageCheckedException
