Configurable retries or exit code when loading secrets fails

[samsternatretool]

I don't know why, but sometimes this plugin fails with this message:

Unable to locate credentials. You can configure credentials by running "aws configure".

This exits the build with code 1. We generally don't retry code 1 in our pipelines because it's not something that will normally succeed on retry. However whenever the build failure is due to this issue, it seems to always pass on retry.

I would love if we could configure the exit code for when this plugin fails to load secrets so that we can differentiate this from actual build/test failures in our pipeline.

Even just passing through the original non-zero exit code might be enough? AWS CLI generally uses things other than 1 for common weird errors.

But the plugin always exits 1: https://github.com/seek-oss/aws-sm-buildkite-plugin/blob/master/lib/shared.bash#L45
