Adds feature enabling Rustls rather than OpenSSL

[azzamsa]

Hi.

Dealing with openssl can sometimes be quite a hassle, especially when it involves the challenge of finding the correct packages like openssl-devel or libssl-devel and so on. There have been instances when I had to install openssl-devel solely to run this app. In my opinion, opting for rustls seems like a promising solution.

It's worth noting that the sqlx-cli project has also taken a similar approach, as seen in their commit here: link to commit.

Lastly, I'd like to express my gratitude for the existence of cargo-udeps. It has proven to be quite helpful. 🏅

I definitely would like to support this, but it's more of an upstream issue. I think there is some discussion inside rust-lang/cargo#8154 about it, at least people there brought up the idea of using rustls in cargo.

Lastly, I'd like to express my gratitude for the existence of cargo-udeps.

Thanks ❤️ ❤️
