Authentication with drf: jwt and socialapps

[Virako]

The authentication should work by API. For example:

• auth/login/

With params, we should look at user in DB and create/return user Token.

params: {
  "email": valid_email,
  "password": pwd
}

return: {
  "token": token
}

• auth/register/

With params, we should create an user in DB, and create user Token for return it.

params: {
  "email": valid_email,
  "password": pwd
}

return: {
  "token": token
}

• auth/logout/

Call logout with token in headers should remove current Token.

headers: {
  "token": valid_token
}

return: "logout success"

When authentication is done, we need to change every tests where we are authenticated.
