Feature: Activate new registered users by making API request

[codesankalp]

Is your feature request related to a problem? Please describe.

For a complete basic authentication system, we need to activate the newly registered users.
When a newly registered user clicks on the activation link sent to the mail it results in a redirection to the Login Page.

Describe the solution you'd like

Create a new URL in urls.js for activating user which will make a GET request to http://127.0.0.1:8000/api/token_auth/activate/< uidb64 >/< token >.

The email for activating user contains URL in this format:
http://localhost:3000/< uidb64 >/< token >.

So you have to add a Route to this URL also to parse it and make a request to the backend and display the response received from the backend.

@isabelcosta After solving these issues:

1. Feature: Activate new registered users by making API request #83
2. Bug: API response for activating users returns 403 Forbidden anitab-forms-backend#81

Registering new users will work perfectly.

Can you add labels to it?
