Confirmed that tugboat is correctly using the cache via console.logs and the debug flag on drupalClient.

[next-drupal][debug]: Returning cached menu items for header-megamenu
[next-drupal][debug]: Returning cached menu items for va-gov-footer
[next-drupal][debug]: Returning cached menu items for footer-bottom-rail
