AWS Lambda end of support for the Go 1.x runtime

[HugeIRL]

The go1.x runtime is being deprecated in favour of the provided.al2 runtime, see this post for background.

We implemented the steps in the blog post the following PR #103 however, at the time the library AWS-Lambda-Go was at an old version that was incompatible with the provided.al2 runtime. After the runtime was upgraded in #107 the changes in this PR should make the scaler work with provided.al2 lambda runtime.

Fixes: #101

Amazing work!

@HugeIRL Thanks so much for your amazing efforts in getting this out. 🙇‍♀️

Will there be a timeline for update of the S3 bucket latest link with the updated v1.7.0 version for BuildkiteAgentScalerVersion param?

[HugeIRL]

@jenniferhopwood I appreciate that, thank you!

We still have some final touches and fixes to do, so once that is done it'll be updated. At the moment no timeline yet, but we are actively working on it! :)

@jenniferhopwood you can use this with the currently released version of the Elastic CI Stack by setting the BuildkiteAgentScalerVersion parameter to 1.7.0.

Edit: I tried this out in the UI, and it didn't seem to work. I then used aws cloudfromation update-stack and it did. Looks similar to buildkite/elastic-ci-stack-for-aws#1172 (comment).

TL;DR use aws cloudformation update-stack to update your stacks.

In any case, it's released with v6.8.0 of the Elastic CI Stack.

I had considered passing in 1.7.0 value but decided to wait before I locked down my versions.
Thanks so much @triarius and @HugeIRL for actioning this we have deployed this version last weekend and this has unblocked us for many of our code scanning tools and improved our AWS Trusted Advisor status.
Much appreciated. 🙇
