Include "External Resource Link" template in course settings to make an external resource visible to staff

[wadefagen]

Many users of the queue will reference an external resource. This can include:

• For advising offices, the student's advising record,
• For courses, the student's github repo and/or gradebook,
• etc.

This feature would add an "external resource link" visible only to staff to link to that student's external resource. This link would need to be templated, allowing a NetID to be substituted into the link. For example, the advising record URL is: https://my.engr.illinois.edu/ugradrecs/select.asp?search={{netid}}
...where {{netid}} would be filled in with the current queue user's NetID
