using python csv module

latin1 is still supported as a fallback when input csv does not decode
as utf8

Split into several test classes for easier maintainance

no need for test_suite everywhere

The cloudooo test on erp5-master is not able to finish after last erp5.util release: https://nexedijs.erp5.net/#/test_result_module/20180719-86977F42

After fix, there is a cloned test suite and the test is completed: https://nexedijs.erp5.net/#/test_result_module/20180719-781978C2 , but some test fails.

I don't know these particular tests neither if they are failing due to the egg release, but the change in this MR solves the problem with test execution and it is ready to merge.
