Unable to enable opentracing

[Stono]

Hey,
With the following configuration options:

  enable-opentracing: "false"
  zipkin-collector-host: zipkin.istio-system.svc.cluster.local

I'm getting:

-------------------------------------------------------------------------------
Error: exit status 1

Closing. Fixed in master #2826
