Description
While the underlying Go network stack supports DNS lookups over TLS, Docker provides no way to specify that the DNS server passed with --dns is capable of DNS over TLS (or if it is desired).
Example code here: https://github.com/artyom/dot/blob/master/dot.go#L44
Sadly, I do not understand the libnetwork codebase well enough to submit a PR.

Research direction
Start by reading the libnetwork code that handles DNS servers supplied through Docker's --dns option, then compare its behavior with the linked dot.go example. Determine how DNS-over-TLS support and user intent would be represented. Done means an agreed implementation supports upstream DNS-over-TLS lookups and has coverage for the configured behavior.
