[cloudwatch exporter] API usage optimization

[Or Shachar]

Hi,

Our company recently hit this issue - with `/metrics` endpoint taking > 20s to load.

I started working on a solution and I saw that big contributions should start with a short discussion here.

Pardon for starting the work in advance. 

I'd really appreciate a short review of the suggested solution.

https://github.com/prometheus/cloudwatch_exporter/pull/414

Also - I wonder if we should migrate to https://github.com/nerdswords/yet-another-cloudwatch-exporter even though it's not under the official Prometheus organization.

Thanks in advance!

So are you intending on trying to move to using the bulk multi-request
API call where possible to reduce the number of calls & make things
quicker/cheaper?

Not sure about cheaper because the pricing is the same (per metric requested).

But for sure it will be much faster. One request of GetMetricData can retrieve the same amount of data as 500 requests of GetMetricStatistics.
