[keycloak-dev] Initial client scopes PR

It's not yet clear... Maybe we can rename tab to "Role Scopes"? Will it 
be clearer or even more confusing? :)

Also I've removed some ClientTemplate model properties, which were never used. Client Scope still has list of protocol mappers and list of "Scopes" (Roles scope mappings).

The scopes configured here will be added as default/optional scopes to new clients. Client can override this (Remove those defaults and add some different client scopes). So it works similarly to Default Roles.

Due the fact, that parameter "Scope Param Required" was removed from RoleModel, the "offline_access" role is now automatically available in tokens for clients with "Full Scope Allowed", even if no offline tokens was requsted. But I don't think it's big issue besides a bit bigger token. Same also already applies for uma_authorization and some other built-in roles. The fact, that offline token is requested is now driven by "offline_access" scope. But user should still have "offline_access"

> - There can be still the case, when client has some protocolMappers or role scope mappings defined on itself. So I've added flag "Display On Consent Screen" on clients (It's OFF by default) to specify if some message should be shown on consent screen about claims dedicated directly to client itself. It's useful especially when client doesn't have any client scopes as the consent screen wouldn't be displayed in that case.

> - During this refactoring, I've tried to do some cleanup we discussed before, so I've removed protocolMappers and roles from clientSession.
> Instead I've added clientScopes to refresh token. During refreshing token, it's checked that user still has all the consents, which are in the refresh token. So in case that user revoked consents in the meantime, the token refresh will fail. ProtocolMappers and scoped roles are always re-computed from the clientScopes. So if for example another claim was added to scope "profile", it will automatically be applied after refreshed token. I don't see an issue with that. User approved on consent screen scope "profile" and he may not be concerned what claims/scoped roles are in profile.

> - Migration: In the end I did not change existing clients and did not remove protocolMappers from them and didn't add default/optional client scopes to them. The only exception is "offline_access" profile, which is added as optional to all clients, which had scope to "offline_access"
> role. Consents are not migrated - again with the only exception being "offline_access" consent, so refreshing offline tokens from previous version still works. The new consent screen is something quite different than previous one, so makes sense to show it to users again when they want to login, even if they approved protocolMappers for the previous version.
