Add course number

[damianhxy]

Description

• Add field to CUD table to store course number
• Display course number where relevant (gradebook / gradesheet / manage students / course profile)
• Update add user to course form to support course number
• Update roster import to support course numbers
• Add "by course" statistics to statistics page

Misc

• Prettify course average tweak section of add user to course
• Left-align emails in gradebook, remove redundant CSV (the classes don't exist, they're all .tip)
• Increase default width of columns in gradebook
• Remove dead reference to assessments_show in show.html.erb
• Lint Form Builder

Motivation and Context

Record course numbers for students, so that students from different courses but in the same autolab course can be distinguished.

How Has This Been Tested?

• Successfully import course number via autolab format / CMU roster format (for a new student)
• Successfully import course number via autolab format / CMU roster format (for an existing student). Essentially, upload the same roster for the previous part, but with some data changed (such as course number). After saving the roster, the changes should be reflected.
• Ensure that import success / error tables show course number (when it exists)
• Ensure that gradebook / manage student tables show course number (when it exists)
• Ensure that add user to course form is able to correctly create user with course number
• Ensure that you can edit the course number of an existing user

Types of changes

• New feature (non-breaking change which adds functionality)

Checklist:

• I have run rubocop for style check. If you haven't, run overcommit --install && overcommit --sign to use pre-commit hook for linting

All of the changes look good, however for users that are added via 'Import roster/users' the course number shows up in the import course roster table

(the row is black, because I re-imported the csv for the screenshot)
but it doesn't seem like the course number shows up with the student

Users added via the 'Add user to course' button do seem to have the course number.

Looks good now, confirmed that users uploaded via 'import roster' had course number, and when uploading an updated csv, the change in course number was reflected.
