Include Route53 HealthChecks

[dougtoppin]

Suggest adding automatic configuration of Route53 HealthChecks for both website and product service.

I am experimenting with this now but having a problem. The healthchecks work fine with an open ALB but if I change the ALB SG to restrict access and add the HC IPs to the SG the product service HC works but the website service HC does not.
Not sure why this is not working yet but I do think having healthchecks are good to act as examples of monitoring the deployed services.

Will update this as I learn more.
