[Studio OIDC & KeyCloak] Scopes requested at login stage are hardcoded #2091

When OIDC (OAuth2Provider or KeycloakOAuth2Provider) is used to authenticate users, scope lists asked during authentication are not defined, so, it seems that one used per default is :

• openid
• profile
• email

Scopes are useful to get user information and map them to Tock roles.

It could be cool to have a property, for example, for keycloak tock keycloak scopes with default values (openid profile email) that can let the Ops define needs scopes.
