* Explore: Transform prometheus query to elasticsearch query
Enable a way to transform prometheus/loki labels to elasticsearch query.
This make a link between metrics to logs.
Examples:
A prometheus query : rate(my_metric{label1="value1",label2!="value2",label3=~"value.+",label4!~".*tothemoon"}[5m])
Will be this elasticsearch query when switching to elasticsearch datasource: __name__:"my_metric" AND label1:"value1" AND NOT label2:"value2" AND label3:/value.+/ AND NOT label4:/.*tothemoon/

* Use prism token instead of regex
* fix test ./scripts/ci-frontend-metrics.sh
* mock timesrv and TemplateSrv in test
