// initializeFieldTagPath traverses the given struct trying to initialize

// lowercased struct field name is used for the metric name. The name is
// prefixed with tags from previous struct fields if any, separated by a dot.
// For example:
//

//              Latency metrics.Timer `metric:"latency"`

//              Latency metrics.Timer `metric:"latency"`
//          } `metric:"http"`
//      } `metric:"messages"`
