[Extensions] Add support for minimum compatible version for extensions with OpenSearch

[saratvemulapalli]

Signed-off-by: Sarat Vemulapalli [email protected]

Description

Part of opensearch-project/opensearch-sdk-java#346.
Added support to define minimum compatible version for extensions talking to OpenSearch.
As we are limiting to minor version compatibility for now, we will revisit this validation when major version compatibility is in the works.
Also, cleaning up unnecessary config needed for extensions as most of it is inherited from plugins back in the day.

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-6003-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 6176ddc0ae831095a0e2e8a38b0f475158abef3b
# Push it to GitHub
git push --set-upstream origin backport/backport-6003-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-6003-to-2.x.

Is this backwards? Why should the server care about the minimum version of a client? I think the extension should be required to provide a declaration for version compatibility and the server should check it.
