We have one jenkins job that deploys multiple applications for us. We're trying to tag the event with each app:{name} value, but currently, only the last value shows up.

Currently, this line https://github.com/DataDog/jenkins-datadog-plugin/blob/master/src/main/java/org/datadog/jenkins/plugins/datadog/DatadogUtilities.java#L280 does not allow multiple values for a given key. Whenever a tag with the same key shows up, it overwrites the previous value. Ideally, I think we'd want to modify the above line to make a data structure of the type:

{
   'key': ['value'],
   'key2:['value1','value2']
}

And change https://github.com/DataDog/jenkins-datadog-plugin/blob/master/src/main/java/org/datadog/jenkins/plugins/datadog/DatadogUtilities.java#L535
to iterate through the value list and add the created string to the tags array.
