[SPDK] [Release] 23.09: NVMe-oF TCP data digest chaining, JSON-RPC Go client, DIF/DIX CRC32/64

On behalf of the SPDK community I'm pleased to announce the release of SPDK=
 23.09 !

This release contains the following new features:

- Accel operation chaining NVMe bdev: The NVMe bdev will now advertise supp=
ort for accel sequences if the underlying controller supports it
- NVMe-oF TCP data digest chaining: The NVMe-oF TCP transport will now calc=
ulate data digest using the accel sequence APIs if they're available.
- JSON-RPC 2.0 client in Go: Added JSON-RPC 2.0 client written in Go to eas=
e communication with SPDK. Please see the https://github.com/spdk/spdk/blob=
/v23.09/go/rpc/README.md
- DIF/DIX CRC32/64 support: Extended util library DIF/DIX support to CRC-32=
 and CRC-64 format of the Protection Information.
- NVMe-oF/TCP TLS configuration: It is now possible to persist NVMe-oF TCP =
TLS configuration across application restarts.
