Introduce a course_tool plugin entry point and migrate the updates, bookmarks and reviews tools into plugins.

NotImplementedPartitionScheme, which allows deprecated partition types to have
a valid entry point despite being unusable.

This reverts commit 1a3f0958.

IMPORTANT: this commit converts the course_groups
package to using migrations.  When deploying to an
existing openedx instance, migration 0001 may fail
with an error indicating that the CourseUserGroup
table already exists.  If this happens, running
the 0001 migration first, with the --fake option,
is recommended.  After performing this step,
remaining migrations should work as expected.
