Fix win_dsc integration tests

[ronger4]

SUMMARY

• Fixed the following failure

TASK [win_dsc : assert test DSC with all types] ********************************
fatal: [windows_server]: FAILED! => {
    "assertion": "dsc_types_actual.DateTimeParam.Value == '2019-02-22T17:57:31.2311890+00:00'",
    "changed": false,
    "evaluated_to": false,
    "msg": "Assertion failed"
}

Ansible couldn't compare properly DATE/TIME formats with different timezones as they are represented as strings, had to add a fix which converts those strings to Datetime.

• Adapted code to fix ansible-lint warnings and errors.
