fix: improves form timer (old)

[thiessenp-cds]

Summary | Résumé

Improves the form timer by handling the case of forms with groups. If a form has groups, the delay calculation includes required questions based on the group history. The time a user spends on a form is now also included in the calculation.
This is a high risk PR since it updates forms-forms submission logic.

Test

The form timer should not display in the form-builder Preview. The form timer is only for forms-forms

Groups Form

Create a form with groups and add a few required questions. View the form you created and open the dev console. Reload the form (to restart the timer) and quickly fill in the form, counting the number of required questions. When you get to the Review page, check the console and see if the final delay makes sense.

For example, a form that has 10 required questions and has been view for 5 seconds, should have a delay of
2 + (10 - 5) * 2 = 12 seconds

Note that the countdown begins once the Review page loads. So if you linger on the Review page for e.g. 5 seconds and then click the submit button, count down delay should start at e.g. 7 seconds (with a total delay listed of 12 seconds)

Non-Groups Form

Create a form without groups and add a few required questions. Following the same steps above. The difference is the time a form is viewed is not taken into account (existing behaviour - countdown begins when the single page form is shown).

I have a question - is it suppose to calculate the time spent on each required question throughout the entire form, prior to the Review Page? Or is it that you need to hang around the Review Page for a certain amount of time (per each required question) before you can submit?

(Asking because when I tested, I waited 10 seconds while filling out each required field. But then when I got to the Review Page, I still had to wait to submit the form?)

This should be left as is, since 0 is intentionally the disabled state. So don't use 0 as the default
