Add versioning support for SDK

[saratvemulapalli]

Problem

We have seen problems across the project that plugins have compile time dependency on OpenSearch which is why they have to be released every version.
opensearch-project/OpenSearch#1707

Why

We'd like to fundamentally solve this problem for extensions i.e SDK to work with multiple versions of OpenSearch.
To launch Extensions SDK we believe it adds value for developers supporting multiple versions of OpenSearch from day1.

How

Minor Version Compatibility Phase 1

• Design and build forward compatibility and backward compatibility for SDK
• Add support to define a range of version compatibility for extensions #346
• [Meta] Move over existing extensions APIs to work across versions OpenSearch#7402
• [Meta] Build a test framework to test cross version extension/SDK. #347

Minor Version Compatibility Phase 1.5

• [Extensions]Versioning support for plugin extension points OpenSearch#2283

Major Version Compatibility Phase 2

• Add backward and forward compatibility support for Major versions
• Evaluate compile time dependencies of SDK and abstract opensearch.core classes (Decoupling)
