Description (What does it do?)

Remove pagination for departments api

How can this be tested?

Create over 12 departments with courses. Go to http://mitxonline.odl.local:8013/api/v2/departments/
You should see all departments on one page.

Oh, does this mean that Urban Studies is coming on the 2nd page?

Is removing the pagination the best solution? What about changing the page size?

Granted, there is a practical limit to the number of departments. The largest possible list is this one, in Learn: https://learn.mit.edu/departments

@pdpinch What is the use value for having pagination for departments? It seems redundant. We want the whole list when rendering the Catalog page.

Oh, does this mean that Urban Studies is coming on the 2nd page?

Yes, and another department "Political Science". Both are missing from the Catalog Page.

If 31 is largest number of Departments and we need all of the departments on first rendering I don't see a reason to have pagination.

Ok, if you and Collin are in agreement that's good enough for me.

What do you think about releasing this today? It's a pretty serious bug.
