"Rate exceed" triggering for frequent builds

[nesta219]

Hi there,

My company uses a monorepo to build/deploy multiple projects at once. As such, we run 10+ checks using this action simultaneously, and if there are multiple PRs building at one time, we often seen failures along the lines of:

Run aws-actions/aws-codebuild-run-build@v1.0.0
*****STARTING CODEBUILD*****
##[error]Rate exceeded
*****CODEBUILD COMPLETE*****

My suspicion is that this is actually the AWS api rate-limiting us on the backend as it makes repeated, simultaneous API calls from the same access key. This issue could probably be solved by either increasing the sleep time during waitForBuildEndTime or simply adding a try/catch block to avoid the process dying if the api call returns a rate limit error.

Looking at this,
my guess is that we are polling too fast.
The tool pings every 5 seconds:
https://github.com/aws-actions/aws-codebuild-run-build/blob/master/code-build.js#L67

Keeping things simple,
I think just pushing this to 60 seconds would be fine.

@seebees that sounds great. I think another solid idea would be to simply wrap the call in a try/catch and then retry, rather than have the entire action fail because one api call was rate-limited

Just sticking in a try/catch is simple, but scary.
Because it has no back off.
So as clients ramp up,
there is never enough breathing room to recover.

I'll throw some comments on the PR,
because the best solution combines this:
Longer wait, slowdown on error.
