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

## What's this PR is about?
Minor fix in args usage message of support flag. The current message
says that the flag should be 'metrics.url' but it reality it should be
'metrics.urls'
