Deprecate Map, List, and Set in org.opensearch.common.collect

[andrross]

Code links: Map, List, Set

These classes have been pass throughs to the java.util since Java 9. They are pretty harmless, except for the annoyance that sometimes your IDE imports the OpenSearch class and then has to fully qualify the java.util versions when you want to use those. The task here is to:

• Add @Deprecated annotations to these classes
• Replace all usages within the opensearch-project/OpenSearch repo with the java.util versions
