Cardano Updates

Two generator functions were generating absurdly long lists of trace
events. These very long lists would then cause heap exhaustion then
they were checked.

The solution was to add a maximum length partameter to these functions
and then add a max list length of 10000 to all the calling sites.

With p2p peerselection and the keepalive protocol we are not that
dependant on chainsync timeout for detecting bad upstream peers.

By bumping the timeout from between 135s and 269s to between 601s
and 911s we change the false positive rate from something that
happens a few times per epoch to something that happens less than
once in a decade.

Exclude shutdown peers in active peers calculations.
It can take a while for peers to exit because blockfetch has to
sync with chainsync as it exits. But we shouldn't count those peers as
active or preferred anymore.

Incase of an error use a shorter timeout when waiting for chainsync to
exit.

Enforce a maximum limit on the number of times we will attempt to
promote a peer to warm. Localroot peers, bootstrap relays and manually
configured public root peers are exempt from this limit.

The clearing of the reconnection counter is delayd until a connection
has managed to be active for a specific time (currently 120s).

Small changes

- Move timeLimitsChainSync to Cardano.Network.Protocol.ChainSync.Codec.TimeLimits
- Add PeerTrustable parameter to timeLimitsChainSync and adjust timeout behavior for trusted peers
- Bump minChainSyncTimeout to 601 and maxChainSyncTimeout to 911
- Add extraFlag type variable to various contexts and handles for extensibility
- Add extraFlags parameter to peer selection and connection management functions
- Add property tests for timeLimitsChainSync timeout validation
