Why revert this whole change instead of fixing the build break?

[rutuja-amazon]

@peternied There are two classes RestHelper and IndexTemplateClusterPermissionsCheckTest that have issues - RestHelper needed a lot of functionality to be added in the back-port and the import paths in this version are different than the later versions. This would need refactoring on classes like ClusterInfo, etc. which will require additional work. If we can revert the changes now - since this is urgently blocking MS changes, I can re-raise a new PR with required refactoring for backport post this version getting stabilised.

There is SSLHandshakeException causing CI failure.

[peternied]

After much consideration and discussion the branch that is being targeted opendistro-1.1* is unsupported, and this code is being used and maintained by a private fork. Rather than gate changes to a fork, it makes more sense for that repository to diverge in the areas its supporting but this repository are not supporting. This avoids having to wait on the security maintainers to review / approve / merge changes - doubly so when these changes cannot be validated by the CI systems in GitHub associated with them.

I am closing out this pull request and the other related pull requests, seperately we will consider how we want to address these branches that are no longer supported, in other OpenSearch Project components the ODFE versions of the codebases were archived whereas this one was copied with all its issues.
