[RFC] JDK 17 Upgrade & JDK LTS

[macohen]

Is your feature request related to a problem? If yes, please describe. This project builds using JDK 8 and 11 today. Updating to JDK 17 would help modernize the connectors and create a clearer path to stay modern and update to the latest JDKs regularly.

Describe the solution you'd like

• Support up to three JDKs - this helps for folks building custom connectors who may not be using a newer JDK yet.
• Keep current with the latest version AWS Lambda supports
• Plan for an EOL for JDK support

Does this seem like a decent approach? Other suggestions? Pitfalls?

Since we will still need to support JDK8, by my understanding we can't use features provided later than that? So we just need to make all the connectors compilable using JDK 17?
