Note this isn't working yet, but I am getting quite a few changes here, so saving state while it compiles.

Quick summary of what I've mentioned on Slack:

1. I would suggest that we bump the version of aws-sdk-go to v1.49.6 in a separate PR and you could put your ExecuteQuery changes on top of it. The reason is that there will be quite a few other changes along with that update, and it might be better if they didn’t take away from the focus of the ExecuteQuery PR. I’ve updated Sarah’s branch/PR with the changes needed for that update: Upgrade aws-sdk-go to v1.49.6 #266 If you’re OK with that, we’ll complete the PR description and mark it as ready.

2. As mentioned above, I was able to base your ExecuteQuery changes on top of the bump-aws-sdk branch, and the frontend query seems to be reaching the backend.

@mitchlee-amzn This looks very promising. We'd be happy to test the implementation as we're eager to use SQL within our ongoing customer projects with SiteWise. Thanks for your work, let us know if we can support in testing and even documenting the final use cases.

+1, please continue your great work.
