  1. extend LedgerQueries with delegMapSize -- to query the effective delegation map size
  2. trace delegMapSize with TraceStartLeadershipCheck
  3. export both utxoSize and delegMapSize as metrics
  4. move all metrics to the cardano.node.metrics namespace. This affects:
    • cardano.node.Forge.metrics
    • cardano.node.ChainDB.metrics

WARNING: breaking change -- see point №4. This also simplifies configuration, making the following unnecessary:

2175: Pass a metrics tracer to teeTraceChainTip r=dcoutts a=intricate

After #2158, it seems that ChainDB metrics were mistakenly being logged to `cardano.node` instead of `cardano.node.metrics`. This PR fixes that.
