Description

Rename opendistro/odfe in docs and strings, packages, API, settings.
Backward compatibility not needed because notebooks backend only exists in opensearch.

Note:
"opendistro" in security index (.opendistro_security) and cluster permissions (cluster:admin/opendistro/notebooks/...) are not changed because of security plugin dependency

How come the directory path in opensearch-notebooks is not changed from com/amazon/opendistroforelasticsearch to org/opensearch if all the files have the namespace change?

Thanks, I missed that.. I wasn't able to build it because of common utils dependency, will change and verify
