New Meshery Nighthawk Adapter

Meshery stands as the canonical cloud-native management plane, rigorously managing the lifecycle, performance, and topologies of multicloud infrastructure. Currently, Meshery manages multiple load generators (Nighthawk, Fortio, Wrk2) to execute Service Mesh Performance (SMP) benchmarks. However, the heavyweight C++ Nighthawk binaries are bundled directly inside the meshery/meshery Go backend container. This statically couples the data plane execution to the control plane, bloating the core image size and preventing independent scaling. This project resolves this architectural flaw by cleanly severing Nighthawk from the core server and wrapping it into an autonomous, standalone gRPC adapter (meshery-nighthawk). To achieve this, I will evolve the existing meshkit/meshes/meshops.proto into a generalized adapters.proto capable of routing both traditional service mesh commands and raw load-generation requests. By the end of this project, Meshery Server will dynamically discover and orchestrate Nighthawk as a first-class out-of-tree component, supported by fully overhauled CLI commands (mesheryctl perf), Helm chart deployments, and a dedicated Meshery UI Adapter chip.
