* Pick timestamp from metric
based on #97 and #80 this provides the posibility to use a metric that has a unix style timestamp as the timestamp of the scraped metric
When deserializing objects we need to take the key json path into account as well like we would do for all the values as well. This allows collections to be defined still with each entry having a separate timestamp (e.g. list of time-stamped log messages).
