benchmark JVM varieties (graal, jdk9, ...) #35
Description
Our benchmarking infrastructure doesn't currently support benchmarking with alternative JVM without "polluting" the main data series. We need update it to add the contents of the system properties "java.vm.name" and "java.runtime.version" as tags that can be used for filtering in Grafana.
We also need to migrate historical data to populate the tags, as grafana makes it impossible (or at least really hard) to to the equivalent of getOrElse in the query to default absent tags.
