django-opensearch-dsl Implementation

[Colin-Seifer]

Changes Elasticsearch to target django-opensearch-dsl on the backend. Includes changes to helm which support a full switch over to Opensearch in the future. Contrary to the branch name, this does NOT change anything with the ccdb5 api. The branch was initially made to run tests on that, but in order to do so, I needed to bring the opensearch branch up to date. This only includes changes to the opensearch branch and targeting django-opensearch-dsl.

Additions

• Added support for django-opensearch-dsl
• Added future support for switch to Opensearch

Removals

• Removes backend support for django-elasticsearch-dsl

Changes

• Queries are slightly slower, so I added some sleep calls in tests to make sure data is available before it's used.

How to test this PR
