Verify CA equivalent in the new API

[alexzaru]

I've noticed that the set_force_verify_ca method, along with other methods, has been removed from the MqttOptions type in the new version. I'm unsure of the equivalent method for set_force_verify_ca in the new version.

In my case, self-signed certificates were used for tests and lower environments, and I need to upgrade to a newer version. I see that I need to use the new ConnectionType::TLS, but I can't find a way to set it to not verify the CA.

Any suggestions how to us thisn ow?

Yes, rustls is the default now and doesn't support disabling CA verification. See more here: https://docs.rs/rustls/0.22.2/rustls/index.html#rustls-takes-care-of-server-certificate-verification

For dev env, you need proxy CA with the signed root certificate, look for mkcert or openssl on how to create those for localhost.

I'll update the documentation on a development environment.
