fix(gadget-sdk)!: prevent duplicate and self-referential messages

[tbraun96]

This pull request includes several changes to improve the network and gossip handling in the sdk module. The updates mainly focus on enhancing the peer connection logic, adding new fields to structures, and refining the message handling process to avoid redundant operations and ensure efficient memory usage.

Network and Gossip Handling Improvements:

• Peer Connection Logic:

  • Replaced JoinSet with FuturesOrdered to manage peer connection tasks more efficiently in blueprint-manager/src/sdk/setup.rs.
  • Added a new method wait_for_peers to handle peer connections asynchronously.

• Structure Enhancements:

  • Added my_id field to NetworkServiceWithoutSwarm and NetworkService structures to track the peer's own ID in sdk/src/network/gossip.rs. [1] [2]
  • Introduced recent_messages field using LruCache to store recently received message hashes and prevent processing duplicates in GossipHandle. [1] [2]

• Message Handling:

  • Implemented logic to reject messages originating from the peer itself to avoid processing self-sent messages in sdk/src/network/handlers/gossip.rs and sdk/src/network/handlers/p2p.rs. [1] [2]
  • Improved message deserialization and added checks to prevent duplicate message processing using recent_messages in GossipHandle. [1] [2]

• Test Improvements:

  • Refactored test functions for clarity and removed unnecessary synchronization barriers in sdk/src/network/mod.rs. [1] [2] [3] [4]

• Dependency Updates:

  • Added lru-mem dependency to manage the LRU cache for recent messages in Cargo.toml and sdk/Cargo.toml. [1] [2]
