What happened:

Inside the recently pushed commit for documentation (#1163), healthcheck annotations are declared to be valid only for NLB while, reading the code, they are also valid for the Classic ELB

Anything else we need to know?:

This issue is partially related to #1181. The documention will be a bit misleading until the PR that solves that issue (#1182) is merged since specifying a lowercase value for the protocol annotation ("http" or "tpc") will create a wrong configuration on the AWS ELB
