Added support tunnel to the devnet cmd. In order to get this to run I
made the following changes:
* Create a public function
* Added non root logging
I have also added commentary to the readme to explain the additional
command line arguments needed to integrate with diagnostics. In summary,
if you set the --diagnostics.url the devenet will wait for diagnostic
requests rather than exiting

- stage_senders: don't re-calc existing senders
- stage_tx_lookup: prune less blocks per iteration - because
random-deletes are expensive. pruning must not slow-down sync.
- prune data even if --snap.stop is set
- "prune as-much-as-possible at startup" is not very good idea: at
initialCycle machine can be cold and prune will cause big downtime, no
reason to produce much freelist in 1 tx. People may also restart erigon
- because of some bug - and it will cause unexpected downtime (usually
Erigon startup very fast). So, I just remove all `initialSync`-related
logic in pruning.
- fix lost metrics about disk write byte/sec
Exposing /debug/metrics and /debug/metrics/prometheus was dependent
on --pprof, which also exposes other HTTP APIs. This change makes it possible
to run the metrics server on an independent endpoint without enabling pprof.
