Protect create2 verification with an auth0 authentication

[marcocastignoli]

• using auth0 I created an Application API + Frontend Application + user database.
• in order to access the /verify/create2 API, a jwt token is necessary. and the user calling the api must have the "verify:create2" permission (set on the Application API) (functionality commented for now)
• in order to send request programmatically the developer needs to create an account and then "login" via cli get the token and send the token
• in the ui the user needs to login, and then a new token is asked every request
• canceling tokens mean to:
  • delete the user
  • set the jwt token expiracy data very short (like 30 seconds)

TODO

• implement tests
• Add instructions in the docs
