The maximum number of peers we will track inventory for.

Since the inventory registry is an efficiency optimisation, which falls back to a random peer, we only need to track a small number of peers per inv for available inventory.

But we want to be able to track missing inventory for almost all our peers, so we only query a few peers for inventory that is genuinely missing from the network.
