Handle Nodes changing identities

[nieznanysprawiciel]

Why:

• We should make only one attempt to initialize session with other Node at the same time. But due to possibility of many identities, we can try to establish 2 session by mistake

In p2p network we never can have full knowledge about other Nodes and we must deal with this situation as good as possible.

Acceptance criteria:

• Find and test different scenarios of problems with identities. Repair bugs if they will be found
• Proposals of scenarios:
  • Node adding/removing identity
  • Node changing default identity
  • We get different information about Node from relay than later during initialization from Node directly
  • Node is connecting from different address than previously (this can happen if other Node is behind NAT and it connected to us directly)
  • Check initialization from different threads to the same Node using different identities
  • 2 Nodes are attempting to connect at the same time
