Feature request: support for dynamically determining responders in opsgenie configuration

[hrancic]

Alertmanager v0.18.0 moved from team field to responders for alert routing in opsgenie.

Having team field was useful for an use case where teams were determined dynamically after the alert fired, but before the alert was sent to opsgenie. If the list of teams responsible for the alert is not know before the alert is created, responders approach is not useful.

Something along the lines of the following solution would be much appreciated:

#names contain comma separated list of teams

responders:
 - names: <tmpl_string>
   type: teams

@simonpasquier This seems like a very fair usecase/request and it was possible to do it before the migration. We've been using the previous alertmanager for the same reason, it'd be nice if we could get the same featureset in the newer version as well.

I agree but I'm not sure yet how it should translate in the configuration file. Splitting unconditionally on commas seems a bit rough.

We needs this feature too.
It will be good to determine responders list when alert is created.

Can we expect this to be implemented?

Is there anything missing from #2685 that prevents this issue from being closed?
