Registration Password Validation

[UnicornChance]

Is your feature request related to a problem? Please describe.

When a user is registering the password checking is after submission rather than before/during supplying the password.

Describe the solution you'd like

Instead of waiting till a user provides a password, supply the password requirements up front or do real time password validation as a user provides their password.

Additional context

Keycloak does not provide an out of the box solution for realtime input validation, however utilizing themes we could in theory create our own implementation of either supplying password requirements or validation.
