LGTM! Thanks for fixing this up.
decodePeers can be called by the installSnapshot RPC handler, which means that a panic could be caused by an external actor by sending malformed input. Instead handle the error and report it back via the RPC response.

decodePeerscan be called by theinstallSnapshotRPC handler, which means that a panic can be caused by an external actor by sending malformed input. Instead handle the error and report it back via the RPC response. This prevents a panic and removes the possibility of an external actor being able to cause a raft peer to panic.The new test would cause a panic before, and now it confirms the expected error is returned.
