Rewritable Tracer Not working for Mongo Driver

[Gaurang-Patel]

Hi ,
I'm trying this below rewriter json for mongo driver to add service tag to my spans, But it is not working .

{
  "mongo:driver": [
    {
      "input": {
        "type": "operationName"
      },
      "output": [
        {
          "type": "tag",
          "key": "service",
          "value": "my_service"
        }
      ]
    }
  ]
}

In my analysis what I've found out is inside RewritableTracer.buildSpan method it is not able to get the rule for mongo plugin as for Mongo spans are generated using CommandListener i.e TracingCommandListener.java

So Mongo Rule is not executed on every command of Mongo and currentPluginName is not set properly in AgentRule.getCurrentPluginName(); so It can't fine rule to rewrite traces.
