This PR: * Added the clippy.toml to configure allowable expect / unwrap usage in tests * Removed as many expect/allow lines as possible from tests * moved a bunch of allows to expects where possible Note: in integration tests, non `#[test]` helper functions are not covered by this so we had to leave a few lingering `expect(expect_used` checks around

This crate is designed for utilities that need to be shared across other crates in the workspace, but should not go in core.
For narrow utility features, the pattern is to add introduce a new feature under [features] in Cargo.toml and then gate it with #[cfg] in lib.rs, as appropriate.
