This reverts commit a67b9f70a16a0f16a842aad84754b245a2480b5f,
reinstating commit cf78660ed35712f9bb7c112f70411179070d7382.
The original commit was reverted because I thought I found
bugs in it while verifying it on Stage, but it turns out that
it was simply misconfigured Stage data that causing errors.
The original commit's message has has been copied below:
This commit completes the program_enrollments LMS app
Python API for the time being. It does the following:
* Add bulk-lookup of users by external key in api/reading.py
* Add bulk-writing of program enrollments in api/writing.py
* Move grade-reading to api/grades.py
* Refactor api/linking.py to use api/writing.py
* Refactor signals.py to use api/linking.py
* Update rest_api/v1/views.py to utilize all these changes
* Update linking management command and support tool to use API
* Remove outdated tests from test_models.py
* Misc. cleanup

This reverts commit af4e7a348a.
After merging the above commit, I was seeing 'internal-error's
on Stage in responses to the Registrar API. I am temporarily
reverting it until I can figure out a fix.

This is the third in a series of commits to create
a Python API for the LMS program_enrollments app.
It does the following:
* Creates api/ folder.
* Moves link_program_enrollments.py to api/linking.py
* Creates api/reading.py for enrollment-fetching
functions.
* Updates rest of app to use api/reading.py when
it was going directly through the models before.
* Other misc. cleanup (isorting, unicode_literals,
line breaks, etc).
Still to do:
* Create api/writing.py and update app to use it instead
of going directly through models.
* Create api/reset.py and api/expire.py, which the management
commands call out to.

This is the first in a series of commits to create
a Python API for the LMS program_enrollments app.
We do some general refactoring, renaming, and clean-up
in order to move toward the creation of that API.

ProgramCourseEnrollments were already unique on
(program_enrollment, course_enrollment) by nature of the
OneToOneField on course_enrollment. However, this only
affects realized enrollments. For waiting enrollments, we
need to add a uniqueness constraint on
(program_enrollment, course_key).
This makes the LMS program_enrollments API compatible with the
Registrar programs API, as specified in the Master's partner
integration guide.
