block forging tracing details at default log level

[dcoutts]

We need to ensure that at the default tracing levels we get the crucial information needed to trace a tx through the mempool of multiple nodes and into a block, to see where it got to.

So at default logging level:

• for TraceAdoptedBlock we must see the block hash and the txids included into the block

For log analysis this lets us correlate the new block hash with the txs that were included into it. From there on we can trace the block hash.

For unrelated reasons we must also trace at default log level:

• TraceNoLedgerState
• TraceNoLedgerView
• TraceBlockFromFuture
• TraceDidntAdoptBlock
• TraceForgedInvalidBlock

These are all rare, but possible failures. These should be logged at "Error" level, not just "Warning".

So it looks like the TraceAdoptedBlock mentioned above ought to be included at the "Informational" severity level, not debug. Our default min severity level for the node is probably going to be set to Informational.

for analysing benchmarking runs we read the blocks <-> tx relation from ChainSyncServerEvent.TraceChainSyncServerReadBlocked.AddBlock events.
probably requires 'MaximumVerbosity' to also print the list of tx ids.
