Change Description

• Add new zipkin support for sending trace span messages to zipkin.
• Enabled by new chain_plugin config options for nodeos and cloner_plugin config options for rodeos
  • telemetry-url
    "Send Zipkin spans to url. e.g. http://127.0.0.1:9411/api/v2/spans"
  • telemetry-service-name
    "Zipkin localEndpoint.serviceName sent with each span"
  • telemetry-timeout-us Default: 200000
    "Timeout for sending Zipkin span."

Zipkin sends zipkin Spans to zipkin via http json on a separate thread. timeout_us can be configured for how long to allow each http post before hitting the time out. Nine consecutive failures will disable the zipkin sender until a restart of application.
