Track 2 - Implement import/export GUI for CommCare

[abarquero]

Current behavior

Currently, the Import from CommCare does not work in Track (UI button is now removed).

In order to support our clients (GOAL) and major prospective INGO clients who are currently using CommCare at an enterprise level.

Expected behavior

We need to support the ability to import CommCare data as:

1. one-way form submission to track;
2. two-way form submission for case management.

Additional details

Point 2) is the main reason our clients are using CommCare and not other tools like Ona or Kobo. This will help TolaData diversify our integrations to support survey form submissions and the more complex case management submissions.
