Implement OAuth Server Metadata
As part of #299 (closed), we want to implement an RFC8414 OAuth Server Metadata endpoint.
We need to add metadata for all supported functionality and endpoints, which fortunately is fairly straightforward, as we've architected this service with autodiscovery in place.
We use an intermediate DefaultServerConfigurationSupplier
to allow
easier implementation, but use the generic
Supplier<ServerConfigurationDto>
for a more generic interface.
Closes #299 (closed).
