Add a new backend store that enables iSCSI targets backed by
S3-compatible object storage (AWS S3, MinIO, Ceph RGW, etc.).
The implementation uses a chunked storage strategy where the virtual
block device is divided into fixed-size chunks (default 4 MiB), each
stored as an independent S3 object. This enables efficient random
read/write access on top of object storage.
Key features:
- Chunked storage with configurable chunk size
- Sparse device support (unwritten chunks treated as zeros)
- Concurrent multi-chunk I/O via errgroup
- Per-chunk locking for safe read-modify-write
- AWS SDK v2 with default credential chain
- In-process gofakes3 test server (no Docker needed)
- 12 unit tests + 2 integration tests
Also updates CI workflow to run S3 backend tests and updates
README with S3 backend documentation.

Go's json.Encode outputs null for nil slices. Handle both null and
empty array in the LU removal verification.

The SCSILu.Path field is not populated during LU creation, so grep
for the file path won't work. Use python3 JSON validation to check
the array length instead.

The gotgt CLI client prepends /v{version}/ to API paths, but when built
from untagged commits the version is a git SHA that doesn't match the
server's version route regex. Use curl to hit the API directly instead.

Add a new "CLI management test" step to the CI pipeline that exercises
the full lifecycle of the new management commands against a running
daemon:
- list target / list lu / list tpgt (read existing config)
- create target -> verify in list
- create lu -> verify in list
- rm lu -> verify removed
- rm target -> verify removed
Each step validates output with grep assertions so failures are
immediately visible.

The OneCommand test expects CDB usage data in REPORT_SUPPORTED_OPCODES
response which is not fully implemented yet.

These tests cause gotgt to hang in CI when the command triggers
an unexpected write-path state. Keep ReadDefectData tests which
are read-only and confirmed working.
