samlauth 8.x-3.3

Warnings:

• This release changes the structure of its configuration object which causes compatibility issues with ACSF - and possibly any other modules which manipulate the samlauth config values at runtime. See #3218856: v3.3 change in configuration values breaks ACSF. It also requires a change to any of your scripts that would populate those config values; see the changelog (or the diff to samlauth.schema.yml) for details.
• If you configure your IdP certificate to be a file/key, a warning "IdP Encryption certificate missing" will show on the configuration screen. This can be ignored; it does not affect operation. See #3220150: (bogus warning) IdP encryption cert as file can't be found

New features:

• Support for Key module for storing keys and certificates: #2915977: Key Management
• Improved support for storing keys/certs as files: the strange hardcoded pathname requirement is now gone.
• Some improvements to multi-cert support (which aligns with the upstream module)
• The User Fields Mapping submodule supports Address
• Some extra security related configuration options (though not because I'm sure they improve security; just to complete the set of supported options).
• Issue #3215961 by tostinni: Add SAMLtest.id documentation for testing
