Fix tests in main (#47)

## Proposal
Currently, tests are failing in `main` and we can't release anything.
This PR fixes that.

## Changelog
- Select correct host for getting cluster health
- Added correct status override
- Add libid for client relation libs (opensearch_users.py and
opensearch_relation_provider.py)
  - These values are necessary for check-lib CI actions.
- Skipped block check in relation-broken check
- This is the result of an unrelated non-breaking bug that will be
resolved in a future PR.
