Add admin upload challenge set page.

[kubeliv]

This pull request adds a hidden page that is only shown to admins. This works by getting the ID token from Auth0, and checking whether the set of roles contains Administrator. If so, it will add a "Upload Challenge Set" menu bar item on the sidebar. This page will show the user a couple of buttons to select a file, then proceed to upload it.

Closes #122. Closes #10.

Before

Before this was implemented, I was manually using a curl command to upload these by copying the access token from the browser.

curl -XPOST -F file=@pentesting.zip https://ctf.cyberliteracyforall.com/api/admin/challenge-sets -H "Authorization: Bearer $ACCESS_TOKEN"

After

Future work

• Might be good to clean up the page in the future, it's pretty ugly at the moment. Given that it's not a page that is accessible by normal users, I think it's mostly fine for the time being.
