Add support for JDK 17

Is your feature request related to a problem?

In opensearch-project/OpenSearch#1276 we have benchmarked various JDKs and concluded that JDK 17 gives a non-trivial performance boost.

What solution would you like?

Add support for JDK 17 by ensuring all tests run in CI/CD on JDK 17.

• Add support for JDK 17 sql#467
• Add support for JDK 17 observability#548
• Add support for JDK 17 cross-cluster-replication#331

Do you have any additional context?

Originally v1.3.0 was supposed to GA with JDK 17, but we ran into a number of issues:

• [BUG] Security plugin transport layer(multi-node cluster) does not work due to missing required reflective access (JDK17) security#1653
• [BUG] de.thetaphi.forbiddenapis.gradle.ForbiddenApisPlugin fails to initialize on JDK17 OpenSearch#2299
• [BUG] PA plugin does not work due to missing required access performance-analyzer#144

For 2.0 we will remove support for Java 8, fix the above issues, upgrade to Gradle 7, and bundle JDK 17.
