[Fix #3483] Adding state duration summary

[fjtirado]

Fixes #3483
Add "kogito_node_instance_duration_milliseconds" distribution summary.
Different to the other two summaries, times are collected in milliseconds rather than seconds

@fjtirado IMO we should record also the number this node has been executed. The reason is because you can calculate the mean (duration) / hits = average so we have an idea of the duration of the node....
min max would be interesting as well.

@elguardian I think this is automatically done by the Distribution summary micrometer. This is an example of what is sent to the elastic search for the proccess instances distribution summary
