Subject: [PATCH] chore(gitignore): ignore `.cargo` directory (#3451)

this commit supercedes #3443.

we use the kubert crate to export a collection of metrics measuring the
behavior of our asynchronous tokio runtime.

in order for this crate to compile, one must set a compile-time flag.
this can be done either by setting the RUSTFLAGS environment variable,
or via a toml file in .cargo/config.toml.

- <https://docs.rs/tokio-metrics/latest/tokio_metrics/>
- <https://doc.rust-lang.org/cargo/reference/config.html#buildrustflags>

this commit adds `.cargo` to the repository's gitignore, so that people
may freely modify cargo configuration as needed when building the
project from source.
