feat: learning paths

[pateljannat]

1. Moderators and Course Creators can create learning paths in their system. They will first have to enable this from the settings.

2. Once enabled, they can then create Programs in the system.
3. To create a program, all they have to do is enter a title. Then link courses to the Program. Only courses that have Self Learning disabled can be added to the Program.
4. Once courses are added, they can then add members to the Program.

5. If a system has learning paths enabled, students will not see the default course list. Instead, they will see the programs list with all the programs assigned to them visible on the page.
6. The programs will have a list of courses displayed in order. Clicking on a course enrolls them in it. But they will have to complete the courses in order. They cannot start the second course in the program without completing the first.
7. They also see their progress in the program on the programs page.
