We could use it everywhere, but it's better to reduce the already big
amount of configuration options the admin is confronted with than the
small problem this option solves.

Reimplement getPreferredTranslation outside of IdPDisco so it's reusable
and much more complete. The new method will search the current, default
and fallback language for a displayable string in various metadata
fields. This should be much more complete and robust than previous
approches. Make it a Twig filter so it can also be used there.

FilterScopes documented behaviour is that hostname is only used as
a fallback when there are no explicit scopes (makes sense). However
the code does not do that but always includes the hostname to match.

This refactors the code so that hostname is only evaluated when
no explicit scopes are there. Also it takes the whole fetching and
parsing of the SSOlocation outside of the inner loop whcih is
inefficient. This is now only done once, and only if needed (when
no explicit scopes present).

To confirm the changes testcases have been added for this and also
for some other cases to reach 100% coverage for the filter.

This auth source no longer supports SAML 1.1 so the ACS code was keeping
track of protocol support with only SAML 2.0 as an option to be added.
Therefore, simplify and set this globally in the class. Keep the outside
interface for now the same where getSupportedProtocols returns as list
of the supported protocol.

Note: if you specify AssertionConsumerService in your config you are
responsible for it having actually bindings that we support. This has
always been the case. This PR makes no attempt to change it (the
specified URLs can even be outside of SSP).

Sometimes we patch or edit a hook to meet our specific needs.
Somtimes this leaves behind a file like FILENAME.orig. The hook
detection login still runs these other files, making for confusing
debugging issues. Use a stricter match on what makes a valid hook name
to avoid these issues.

* Allows custom logging handler on the console

This is useful for reducing noise during tests
