This implements a ban manager that tracks client ips and their associated infractions. Associated tests have been added.
This adds a broadcast rate limiter for clients to control frequency of broadcasts made by clients.
This updates tatanka handlers to punish clients sending malformed messages, spamming broadcasts or impersonating nodes by posting to restricted topics like the clients ban and oracle topics. Unauthorized errors now propagate to the client to terminate it.
This restructures infractions by gossiping infractions immediately to the mesh, this way mesh nodes keep an equivalent infractions dataset. Also connecting nodes on startup request for an infraction snapshot, via the infractions snapshot protocol, from one of the mesh nodes picked at random. The ban manager ensures infractions are deduplicated by checking if an infraction key exists for an infraction or not. Associated tests have been updated accordingly and an integration test for new nodes joining a mesh and requesting an infraction snapshot has been added.
This updates client message publishing to return a response in order to be notified of infractions when publishing messages.
This adds a feature to the test client where it publishes spam for the purposes of testing out broadcast restrictions. The harness has also been updated to allow toggling this feature when needed.
