Actually skip flaky tests on CI and in Docker (#626)
Flaky proxy tests were not actually being ignored properly. This is due to our use of a Cargo workspace; as it turns out that Cargo doesn't propagate feature flags from the workspace to the crates in the workspace (see rust-lang/cargo#4753). If I run `cargo test --no-default-features` in the root directory, the `flaky_tests` feature is still passed, and the flaky tests still run: ``` ➜ cargo test --no-default-features Finished dev [unoptimized + debuginfo] target(s) in 0.0 secs Running target/debug/deps/conduit_proxy-0e0ab2829c6b743f running 13 tests test fully_qualified_authority::tests::test_normalized_authority ... ok test ctx::transport::tests::same_addr_ip6_compat_ipv4 ... ok test ctx::transport::tests::same_addr_ipv4 ... ok test ctx::transport::tests::same_addr_ip6_mapped_ipv4 ... ok test ctx::transport::tests::same_addr_ipv6 ... ok test telemetry::tap::match_::tests::http_from_proto ... ok test inbound::tests::recognize_default_no_ctx ... ok test telemetry::tap::match_::tests::tcp_from_proto ... ok test telemetry::tap::match_::tests::tcp_matches ... ok test inbound::tests::recognize_default_no_loop ... ok test transparency::tcp::tests::duplex_doesnt_hang_when_one_half_finishes ... ok test inbound::tests::recognize_default_no_orig_dst ... ok test inbound::tests::recognize_orig_dst ... ok test result: ok. 13 passed;
