Support up to 3 parallel compact block txn fetchings
A single outbound slot is required, so if the first two slots
are taken by inbound in-flights, the node will reject additional
unless they are coming from outbound.
This means in the case where a fast sybil peer is attempting to
stall out a node, a single high bandwidth outbound peer can
mitigate the attack.
