Apache bRPC 1.17.0

Apache bRPC 1.17.0 is a feature release centered around performance optimization, highlighted by the introduction of SingleIOBuf for efficient FlatBuffers serialization/deserialization. This release also expands protocol and transport capabilities with native Redis Cluster channel support, a new transport layer for communication protocol extensions, and RDMA ECE support. Additional improvements include rate-limited backup request policies, error rate threshold for punishment attenuation, and bthread priority queue support. The release further delivers critical bugfixes for use-after-free issues, ARM memory visibility, and Protobuf compatibility, alongside multiple stability and fuzz testing enhancements.
