This removes the portion of the CCX course names data migration
that triggers course publishing. While course publishing is the
desired behavior, doing so within the migration makes it so that
this migration is not practical to run if you have hundreds or
thousands of CCX courses (we run out of memory).
By doing the data migration without the accompanying course
publishes, this means that CCX course names will still show up
incorrectly for courses until there is an edit or publish of
either that CCX course or the underlying course that the CCX
course extends. But we at least set up the data so that it's
gradually self-correcting over time, and do so with little coding
effort or operational risk/weirdness.
A more comprehensive fix for this would involve:
* Fixing the memory leak around CourseOverviews creation and/or;
* Moving CourseOverview generation to happen asynchronously and/or;
* Being more careful about transactionality in the data migration
and running it repeatedly until it all passes.

Django 2.0 will make this field required for `ForeignKey` and `OneToOneFields`.
In previous versions the option defaulted to `models.CASCADE` when not
specified. This change should make the deprecation warnings in the current
Django version go away.
The migrations where also modified, but the changes should not cause a change in
the database schema since `models.CASCADE` was already the old default.
Without this, when CCX runs 0003 it'll invoke course_overviews while
loading a course, but that table has a model change, and the migration
has not run yet. This ensures the course_overviews migration happens
first.
Final official name is Custom Courses for EdX (CCX), rename all code to remove previous name.
Rename the FEATURE constant used to identify this feature
Rename the middleware for the CCX change
rename the constant used for storing the current poc id on the session.
rename the _PocContext threading local
rename the override provider in all places where it is referenced
`PersonalOnlineCoursesOverrideProvider` -> `CustomCoursesForEdxOverrideProvider`
generally rename symbols from overrides.py to replace `poc` with `ccx` where possible without changing model names or attributes
rename more symbols from poc to ccx
rename util functions from app utils module
general symbol renaming poc -> ccx in views.py and related url changes
Rename the coach role wherever it is used.
reword poc_coach to ccx_coach
UI rename
replace POC with CCX globally
template context variable renamed
rename poc_ to ccx_ in urls and all related locations (views, js, scss etc)
remove pocs migrations
Final massive renaming, including models. Re-built migration.
