Add control panel to workspaces

[kenetec]

Summary
Create a control panel in the "Workspaces" page that toggles features of the site.

Problem/Current Functionality
Not every chapter does recruitment the same way we do, therefore we should provide a control panel for directors to customize their experience.

Solution
Create a control panel that toggles these settings:

• Enable/Disable referrals

Acceptance Criteria / User Stories

• As a director, I should be able to toggle referrals.
