Support for SslBundles

[johkin]

Is your feature request related to a problem? Please describe.
I would like to be able to use the new SslBundles that came with Spring Boot 3.1

Describe the solution you'd like
Instead of specifying keystore/truststore for the HttpClient, I would like to be able to just set the bundle name.

Describe alternatives you've considered
My setup today uses a mix of using a bundle for the server configuration and specific keystore/truststore för the httpclient.

Additional context

That would be a nice feature. In addition to that, it would help implementing hot reload for certificates.
