jenkins.job.waiting is in seconds, not ms

[pascalrobert]

The README says the jenkins.job.waiting metric is in ms, but the actual code is converting the values to seconds:

datadog-plugin/src/main/java/org/datadog/jenkins/plugins/datadog/listeners/DatadogBuildListener.java

Line 212 in b84a170

metrics.gauge("jenkins.job.waiting", TimeUnit.MILLISECONDS.toSeconds(waitingMs), hostname, tags);

Please adjust the doc to specific that it's in seconds, not millis.
