Use RecentlyActive feature to only list metrics older than 3 hours when necessary

I have the problem that a lot of the dimensions on my CloudWatch metrics change frequently. Because the default behaviour of listMetrics() is to return every metric that matches your query and has been updated in the last 2 weeks, this causes the scrape time to be very high. With this option, we can limit the returned metrics to only those which have been updated in the last 3 hours. I also had to update the AWS SDK to allow this, as the version currently being used doesn't have this feature

If we're using this it shouldn't be configurable, we already know the range_seconds in use.

[bemica]

So you would suggest to set this option if range_seconds < 3 hours? I guess that also makes sense

[brian-brazil]

Yes.

[bemica]

@brian-brazil I agree that's a lot simpler actually. Changed it to do that and updated the test to make sure that it's actually still possible to get metrics older than 3 hours with this setup

I see this was also talked about in this open issue but never pursued further. With regard to the concern with S3 and similar metrics, I think it's okay because for those metrics the range_seconds has to be very high anyways #134 (comment)_

Hey @brian-brazil
What is your policy on building new releases? ;)

[brian-brazil]

As-needed basically, I've added it to my todo list.

Hi @brian-brazil should we expect a new release with this in the next week(s), month(s)? Thanks.
