discovery uri, seems to be hardcoded

[Pablo Vidaurri]

I need to use a different discovery uri for an Azure B2C instance using a custom flow.

org.pac4j.oidc.config.AzureAdOidcConfiguration:

@Override
public String getDiscoveryURI() {
return "https://login.microsoftonline.com/" + tenant + "/.well-known/openid-configuration";
}

Anyway to get around this without have to rebuild ths lib.
