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

This is the beginning of the series of changes to make it possible to
run multiple instances of erigon inside a single process (as devnet tool
does), with the logging from these processes going to respective log
files correctly.
This is the first part where the initial infrastructure is being
established

To expose context flags through diagnostic endpoint
`/debug/metrics/flags`.
The current `/debug/metrics/cmdline` only provides the command run by
user. In the case when user runs Erigon using config file, `cmdline`’s
info does not truly reflect the ‘launch setting' and flags set that
Erigon is running on.
## Example
### Command
```
erigon --datadir /tmp/data --config test.yaml
```
### Pseudo config file (in yaml)
```
datadir : '/tmp/data'
chain : "sepolia"
http : true
metrics: true
private.api.addr : "localhost:9090"
http.api : ["eth","debug","net"]
```
### Output
```
SUCCESS
chain=sepolia
config=test.yaml
datadir=/tmp/data
http=true
http.api=eth,debug,net
metrics=true
private.api.addr=localhost:9090
```
