Contributions summary:Kazunobu primarily focused on removing dependencies, specifically the `libp2p` library, from the `substrate/client/network` and `sc-authority-discovery` components of the Polkadot SDK. This involved modifying code in several files, including `engine.rs`, `request_responses.rs`, and `kad.rs`, to replace `libp2p` types with network backend agnostic types. Furthermore, the user contributed to migrating pallet-democracy benchmarks to the benchmark v2 syntax, enhancing the testing infrastructure. The user also removed the collation-generation subsystem from validator nodes by using a `DummySubsystem`.
