No default value lookup for OIDC/SAML providers
Concerned version
Version: %2.0
Summary
When creating a OIDC rp or a SAML sp from the CLI (lemonldap-ng-cli), most metadata options are not set (oidcRPMetaDataOptionsIDTokenSignAlg, oidcRPMetaDataOptionsIDTokenExpiration...)
Instead of using default ciphers and duration, the portal code sets null values, leading to errors
Possible fixes
We should probably add subkey default values in ::Common::Conf:DefaultValues and use them in the issuer code when provider options are undefined.
