[keycloak-dev] Manage accounts page

It would be good to have a manage your account page for Keycloak Basically it's a place that let's you: * View and change your user profile * Change your password * Manage OTP (enable/disable) * Manage social accounts (view linked, add/remove) * View audit history For social login if "review profile on social registration" is enabled for the realm we can simply forward the user to this page on first login + it's also a nice place to manage linking multiple accounts.
