Add nanosecond timestamp + workflow info to environment events

[teo]

This PR does 2 things:

• OCTRL-917 - adds a new WorkflowTemplateInfo field to all EnvironmentEvents pushed to Kafka, that includes the public trait of the workflow template as requested, plus the name, description and workflow path.
• OCTRL-918 - in addition to the millisecond timestamp, adds a nanosecond timestamp field timestampNano to all events pushed to Kafka. The timestamp itself is identical to the existing ms timestamp, it is just outputted with higher precision.

good for me, but I will wait for Martin or George's confirmation before merging.

@knopers8 So if I understood correctly, if event.environmentEvent.workflowTemplateInfo.public is false, it should not be stored in Bookeeping?

[knopers8]

@martinboulais I would even go further, I would require event.environmentEvent.workflowTemplateInfo.name == "readout-dataflow". In the ECS GUI you can notice also the template qc-server-workflow and as far as I know, it should not be recognized by BKP (and historically was not).

[martinboulais]

This seems a bit too hacky to me, no? I don't really like the hardcoded values like this, especially when it's from another service.
Why not simply marking the public to false in the workflow template?

[knopers8]

But then qc-server-workflow will not be public anymore, i.e. it will disappear from COG.

I think we want to deprecate it anyway, but to me this is irrelevant to the fact, that we may want to run an environment which is not used for data-taking, but it should be possible to do that with COG.

[knopers8]

What I think would be the best is to add another field/variable in the templates such as bookkeeped and WorkflowInfo would include it.

@knopers8 @martinboulais I think the suggestion to add a new field makes a lot of sense. The current WorkflowPublicInfo value is to let the AliECS GUI know if it should be displayed or not in the env list. Storing in bookkeeping is similar but not fully equivalent, so a new WorkflowStoreInBookkeeping or something like that makes sense.

[martinboulais]

@vascobarroso @knopers8 I agree that adding a new field makes quite some sense to me.
