[keycloak-dev] Manage accounts page

[Stian Thorgersen]

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.
