Implement POST /users

[OmalPerera]

HTTP POST request to http://localhost:8090/api/users should create a new user.

Request schema 1:

{
    "email": "admin@letmehack.lk",
    "password": "password"
}

If the password is not set, you should randomly generate a password in the API backend.

Response schemas:

Status 201: Return if the user was successfully created.

{
    "self": "http://localhost:8090/api/users/{user_id}",
    "email": "admin@letmehack.lk"
}

Status 400: Return if email is not set.

Status 409: If the user already exists.

{
    "status": 409,
    "message": "A user with email: {email} already exists.",
    "developerMessage": "User creation failed because the email: {email} already exists.",
}

Request schema 2

{
    "email": "admin@letmehack.lk"
}

Here the password is not set.

Response schemas

Status 201: Return if the user was successfully created.

{
    "self": "http://localhost:8090/api/users/{user_id}",
    "email": "admin@letmehack.lk"
}
