Summary:
Avoid using plain HTTP and use HTTPS instead.
To do this config needs to provide paths to server certificate and private key files in PEM format.
Then they will be converted to Pkcs12 archive.
This diff adds authentication of server i.e. client can check that it talks to a real server. Next diff adds authentication of a client.
Lower-level `hyper::server::Http::bind_connection()` is used instead of `hyper::server::Http::bind()` method in order to add TLS support.
See code comments for more details.
Implementation is more complicated than I expected it to be. I need to use 3 more new crates. Lmk if there is a better way to do this.
