No status indicator when creating a new Contact

[weaponsforge]

Description

• No indicator shows the new Contact creation status after pressing the SAVE CHANGE button in the /contacts/add page.
• Users are inclined to press the SAVE CHANGE button more than once, or continuously edit the values in the first_name, last_name, phone_no and other Contacts input fields, believing their new Contact is not being currently created

We should display more status information to users when creating a new Contact:

• Disable the first_name, last_name, phone_no and other Contacts input fields and the SAVE CHANGE button after pressing the SAVE CHANGE button
• Display a loading indicator after pressing the SAVE CHANGE button
• After the create new contact async process finishes with a success:
  • Display a SimpleSnackbar notification (or any success message) to the user
  • Re-enable the disabled first_name, last_name, phone_no and other Contacts input fields and the SAVE CHANGE button
  • Remove the loading status indicator

Please view the attached video of the current Create New Contact process for reference.
