Enable using OS certificate store with rustls

Closes #224.

I ran cargo update since I didn't know the command to just update the lockfile after changing Cargo.toml, but it worked and created no additional test failures so I've left that. If you want the smaller set of Cargo.lock changes let me know.

Two tests fail, but they also fail for me on master:

• basic_auth_from_session_is_used
• bearer_auth_from_session_is_used

Is there any additional setup required for the tests?

Can you target develop instead of master?

That might get rid of your local test failures too, I think I remember netrc files affecting those tests before #207.

I ran cargo update since I didn't know the command to just update the lockfile after changing Cargo.toml, but it worked and created no additional test failures so I've left that.

The lockfile is automatically updated after a rebuild (e.g. cargo test, cargo check, etc), so you shouldn't have to take any special action.

If you want the smaller set of Cargo.lock changes let me know.

Running cargo update every once in a while is good practice, but in this case it seems to have messed with our minimum version requirement, so could you try the smaller set?

Done, and that did resolve the test failures. Also removed the cargo update changes.

TIL!
