* Remove email placeholder

The current placeholder is confusing to users and results in many trying
to login with their username. The change in this PR hopefully decreases that
confusion.

According to UX recommendations, we have decided to remove the email placeholder for the form. It seems placeholders tend to just confuse the users.

Update wording on Contact Us page

The upgrade to Django 2.2 has caused a spike in production logging due to RemovedInDjango30Warning deprecation warnings. For now, turn off logging of DeprecationWarning, ImportWarning, and PendingDeprecationWarning whenever we're using WSGI (they'll continue to be logged in devstack). We may eventually want this behind an easily flipped toggle, but for now just remove it to get this resolved quickly.

See ARCHBOM-1141 for details.  Effort required to upgrade pip.

The courseware_api view will use check_course_access - which now returns AccessResponse objects, and all other uses of check_course_access will now use check_course_access_with_redirect, which is a drop-in replacement for the original check_course_access implementation.

We also added a few new helpers to access_utils:

- check_public_access is a replacement for allow_public_access, which now returns AccessResponse objects
 - check_enrollment checks if the learner is enrolled, and uses check_public_access to account for COURSE_ENABLE_UNENROLLED_ACCESS_FLAG
- check_survey checks whether there is a required survey that the learner must complete prior to accessing the course.

There are two new kinds of AccessError subclasses:

- SurveyRequiredAccessError
- EnrollmentRequiredAccessError
