How to test

In #6 I added tests.

In tutor:

• Use a tutor environment with edx-platform with nau/lilac.master branch
• Use nau-openedx-extension (this branch)
• You need to add the following settings

  FEATURES.update({
  "ENABLE_OTHER_COURSE_SETTINGS": True
  })
  OPEN_EDX_FILTERS_CONFIG = {
      "org.openedx.learning.course.enrollment.started.v1": {
          "fail_silently": False,
          "pipeline": [
              "nau_openedx_extensions.filters.pipeline.FilterEnrollmentByDomain",
          ],
      },
  }

• Create a course on the platform
• Go to studio > the course > settings > advanced settings (example: http://studio.lilac.edunext.link:8001/settings/advanced/course-v1:edX+DemoX+Demo_Course) and add in other course settings:

  {
  "filter_enrollment_by_domain_list": [
      "domain1.com",
      "domain2.com",
      "example.com"
  ]
  }

• Create a user with a domain or subdomain in the filter_enrollment_by_domain_list, and the user will be able to enroll
• Create a user with a domain, not in the list, and the user won't be able to enroll
• You can change the lang preference, and the UI message error will be in the correct lang

This PR is ready for review.

• The fnmatch for subdomains was added.
• The exception message can be showed in the user interface with this PR #4 in edx-platform
• And I add unit test for this functionality and for the wrapper in this PR #6

If you are okey I am going to squash the commits in this PR and merge when I have the approval
