Update user

This works only when a user has UPDATE right on users, a guest profile cannot update himself from the API currently, see GLPI issue #2568.

The agent may update user information like phone number, emails, name.

This can be done with the endpoint User. Only fields requiring an update should be specified.

PUT apirest.php/User/:id

{
    "input": {
        "firstname": "new firstname",
        "realname": "new realname",
        "phone": "0123456789",
        "phone2": "0987654321",
        "_useremails": {
            "0": "email1@example.com",
            "1": "email2@example.com"
        },
        "_default_email": "1",
    }
}
