Describe the bug
I can't use trust-dns-client with rustls 0.20.0

To Reproduce

use trust-dns-client `0.20.3
use rustls 0.20.0
Create rustls::ClientConfig:

  let config = rustls::ClientConfig::builder()
    .with_safe_defaults()
    .with_root_certificates(root_store)
    .with_no_client_auth();

Try to create HttpsClientConnection:

  let x = HttpsClientConnection {
    name_server: doh_socket,
    dns_name: "dns_server.pl".to_string(),
    client_config: config,
    marker: PhantomData,
  };

Compile and get error:

error[E0308]: mismatched types
  --> src/main.rs:70:20
   |
70 |     client_config: config,
   |                    ^^^^^^ expected struct `rustls::client::ClientConfig`, found struct `ClientConfig`

For more information about this error, try `rustc --explain E0308`.
error: could not compile `malw` due to previous error

Expected behavior

OS: [macOS]
Architecture: [x86_64]

This is expected. You can use released trust-dns with rustls 0.19 for now or trust-dns from the main branch if you need rustls 0.20.
