Ability to check if the user signing up exists already

[nabilshuja]

Problem

Currently, I think if you try to sign up right now using existing credentials, while the API does respond with an error. It's not feasible enough to check through exc/ exception that the mobile exists/ primary key exists / email exists. And while server messages are fine. Translation for them is an issue.

Solution

Having a separate API for checking whether or not a user exists. Based on email & phone number. And maybe even check for enabled or not, I suppose. I believe this would be useful in other cases as well.

is it possible to update login response if the user exists ? in order to avoid making two api calls each time.
