OpenSearch client relation hooks & helpers.
See this link for a detailed spec: https://github.com/canonical/charm-relation-interfaces/tree/main/interfaces/opensearch_client/v0
The read-only-endpoints field of DatabaseProvides is unused in this relation because this concept is irrelevant to OpenSearch. In this relation, the application charm should have control over node & index security policies, and therefore differentiating between types of network endpoints is unnecessary.
A role will be created for the relation with the permissions and action groups applied, and these roles will be mapped to a dedicated user for the relation, which will be removed with the relation. Default security values can be found in the opensearch documentation here: https://opensearch.org/docs/latest/security/access-control/index/.
