Add support for JDK 17 #142
Description
In opensearch-project/OpenSearch#1276 we have benchmarked various JDKs and concluded that Java Runtime 17 gives a non-trivial performance boost. Therefore, coming from opensearch-project/opensearch-plugins#129, add support for JDK 17.
- Add JDK 17 to CI/CD, do not remove 11 and 14.
- Update DEVELOPER_GUIDE and any other notes on Java runtime compatibility.
