an idea to support dynamic https like (caddy server)

[ashraf-revo]

Motivation

i hope if we could support tls lazy load certificates by domain
this might help us in renew the certificates (using letsencrypt or other)
support dynamic https like (caddy server)
see https://caddyserver.com/docs/quick-starts/https

Desired solution

add function to load certificates by domain as key
we could implment this function to renew or generate ssl certificate

@violetagg after check the code i found that it could be done if we create new method SniProvider.newSniHandler
that use the io.netty.handler.ssl.SniHandler not reactor.netty.tcp.SniProvider.AdvancedSniHandler because it not use the power of AsyncMapping<String, SslContext> and overide io.netty.handler.ssl.SniHandler.lookup to return Future<SslContext> from pre passed function Function<String,Future<SslContext>>
