Add push contacts for rapidpro

[megh-k]

The files that need to be checked are

• casepro/backend/rapidpro.py specifically the push_contacts function Adding urls to sync here and here Function to push contacts to rapidpro here Calling push contact and setting the UUID for the new contact from rapidpro here
• casepro/backend/tests/test_rapidpro.py Testing needs work here
• casepro/contacts/models.py In the models the uuid is retrieved from rapidpro and set to the casepro contact here

Description for the RapidPro devs: The push_contact function was necessary for the Open Case button functionality. For this to work a few things are necessary, as summarised below:

• URNs need to be synced to CasePro to check if the URN already exists in both CasePro and RapidPro.
• URNs also needed to be hidden from the UI for privacy. I removed the urn.path from the frontend but left the placeholder.
• push_contact checks for the contact in RapidPro by the URN, if it doesn't exist, the contact is created in RapidPro and the RapidPro uuid is returned.
• get_or_create_from_urn looks for the contact in CasePro by the URN, if it does not exist, it gets the contact from RapidPro and its uuid, it then looks for the CasePro contact by the uuid to avoid duplicated, if it still doesn't exist, a new CasePro contact is made and the uuid is set to match the RapidPro uuid.
• As we make use of WhatsApp, the WhatsApp scheme is also added as a valid scheme.
• The test were also updated to accommodate the new functionality.
