Especially during development these contain application errors and should be more visible

Add ledgerCumulativeTxBytes to LedgerQueries and wire it through LedgerMetrics so that the periodic ledger metrics trace emits an IntM "cumulativeTxBytes" gauge. This creates a Prometheus metric cardano_node_metrics_cumulativeTxBytes_int that can be used with rate() to compute confirmed tx throughput (txkB/s). The field is read from shelleyCumulativeTxBytes on the ShelleyLedgerState (added in ouroboros-consensus on the cumulative-tx-size branch). Byron returns 0. Picks up shelleyCumulativeTxBytes, the new top-level field on ShelleyLedgerState that tracks cumulative transaction bytes on the selected chain.
ouroboros-consensus#1988 has merged, so point the SRP at the tip of leios-prototype
…es-metric Expose cumulative tx bytes as a Prometheus metric
Otherwise we can't compile due to

Description
This PR hosts changes to cardano-node related to Leios. I'm opening a PR for easier management and transparency to make changes visible at a glance.
More importantly, this branch will be tagged and sourced for Leios demos.
IT IS NOT INTENDED TO BE REVIEWED OR MERGED!
