docs(e2e): write contributor guide for e2e_test crate (backlog#1153 infra-10)
Turn the e2e_test README skeleton into a dense, link-heavy contributor guide:
crate overview + grouped module map, how to run (whole crate / one module /
e2e-smoke profile / ILM serial lane / protocols suite), #[ignore] semantics as
a pointer to live sources, how to add a test (RustFSTestEnvironment +
RustFSTestClusterEnvironment, common.rs/chaos.rs helper inventory, isolation
rules, #[serial]-vs-nextest reality), a CI subset map table, and a
troubleshooting section (stale binary / RUSTFS_TEST_PORT / orphan processes).
Keeps the ci-4 "CI smoke subset" section intact and restructures around it.
Adds a reciprocal link from crates/e2e_test/AGENTS.md.
Refs rustfs/backlog#1153 (infra-10), #1155.
ci: run e2e smoke subset via nextest e2e-smoke profile (backlog#1149 ci-4)
The e2e-tests job previously ran a single test (delete_marker_migration
_semantics) out of ~400 in the e2e_test crate. Define a nextest
profile.e2e-smoke whose default-filter selects 17 fast single-node
dependency-free modules (63 tests) and run it in the job, reusing the
downloaded debug binary. The profile is the single wiring mechanism for
e2e tests in CI; admission criteria live in crates/e2e_test/README.md,
and docs/testing/e2e-suite-inventory.md records authoritative per-module
counts from cargo nextest list.
This commit introduces a significant reorganization of the project structure to improve maintainability and clarity.
Key changes include:
- Adjusted the directory layout for a more logical module organization.
- Removed unused crate dependencies, reducing the overall project size and potentially speeding up build times.
- Updated import paths and configuration files to reflect the structural changes.
