Add a post authenticaton handler to validate email domain during federated authentication

[Yasasr1]

Proposed changes in this pull request

This pr introduces a new post authentication handler to validate the email address of the user authenticated from a federated IDP.

This handler will be invoked when email domain based organization discovery is enabled to prevent user authentication and provisioning to organizations when the authenticated user's email domain does not match with any of the mapped email domains for the organization.
