Add Email Field to User Registration

[bbroklyn]

Description

Currently, the user registration process in Keycloak requires only a username and password. To enhance user experience and facilitate account recovery, I propose adding an email field to the registration process.

Proposed Changes

1. Update Registration Endpoint:

   • Modify the registration API to accept an email parameter in addition to the existing username and password.

2. Email Validation:

   • Implement validation.

3. Update User Model:

   • Ensure the user model in Keycloak includes an email field to store the email address.

4. Send Confirmation Email

   • Consider implementing functionality to send a confirmation email to the user upon registration to verify their email address.

• Now the user needs to enter his valid email when registering.
• When a user logs into his account, he can enter his email instead of username.
