Description

## Task summary

The `seen` map in `dot/network/gossip.go` does not have a limit of size and no key is ever deleted.

It should be investigated:

1. If there is an event indicating the key can be deleted
2. If not, find a mechanism based on space+time to remove older elements

This issue has not been assessed yet.
