We want to start adding metrics to ldr txn mode, including the existing metrics. Txn mode is implemented as individual sub systems which will cause a dependency cycle if we attempt to import the original logical package. This change extracts the existing metrics struct to its own package. Release note: None

This change adds metrics to see in flight transactions in the applier pipeline. The number is broken down into blocked and ready txns. The former represents the number of txns that are blocked on either another txn or the event horizon. The latter represents the number of txns that are ready to be commited but haven't yet, i.e. on the ready buffer. Both gauges live on the parent metrics.Metrics struct as TxnApplierBlockedTxns and TxnApplierReadyTxns. The applier takes a *metrics.Metrics pointer at construction and updates the gauges directly. Release note: None
