Summary

ENG-5556
Add the backup client to the native_rust library. We activate different features depending on a platform - on iOS we can use the native tls implementation but on Android the native tls reqwest feature pulls in openssl (beause it's linux) and it conflicts with our openssl during linking process. Because of that we replace it with a pure-rust implementation rustls-tls.

Depends on D10261

Test Plan

Test that the app compiles on an physical Android and iOS devices.

Harbormaster failed remote builds in B24906: Diff 34440!

Move the target dependant features to backup_client to check if that fixes the CI issue

Try adding resolver = 2 (but that should already be the default based on the edition...)

Try always setting rustls-tls

Try installing pkg-config on the CI runner

Using @atul suggestion from ENG-5556, I just added pkg-config to buildkite android config. I couldn't figure out a better solution...

just to confirm, devs don't need to install anything new in their local environments, right?

we already have an android feature. do we really need to add logic conditioned on the target os?

Looks like pkg-config is included in nix config link, so I don't think so

One problem with that is that features are additive and the default feature will still be active on android, which was the whole point of adding this code (openssl build issues on android).

In general I find it weird that we have an android feature. Is there some explicit reason for it? Rust has a builtin way to conditionally run code/ include dependencies based on the platform so I think we should use it.

default-features = false solves this, but i understand your point

I think the android feature is weird, too. I'm going to remove it and follow your approach instead.
