[FEATURE] - Integrate new ledger query "queryDRepDelegations" #974
Description
What
Ledger has implemented a new query for queryDrepDelegations that need to be integrated into API a later on CLI. This query returns the delegators delegated to each DRep, including AlwaysAbstain and NoConfidence, and alternatively can be filtered by specific DRep credential.
Why
It's very useful information for both, dreps and delegators to learn, not only the total stake delegated but also the individual stake holder that are delegating to each DRep.
Note: This query is being integrated in cardano-node-10.6.0, so it will not work on any previous versions.

Definition of Done (DoD)
- Acceptance Criteria + User Stories & DoD created and singed-off (by PO, dev & test owners)
- Builds successfully on CI
- Code & Test review (as per Acceptance Criteria)
- There is documentation and/or examples for the new functionality (usage/response)
- Log/record changes on Vnext (or similar depending on what we adopt)
- Ticket number(s) included in PR description
- All Acceptance Criteria met and covered by dev/unit/property/integration tests
- System/E2E automated tests + System Test Engineer Owner Sign-off
NOTE: Ideally, we should merge only fully implemented and tested features into the master branch.
So all the above steps are required for the PR to be merged.
In order to avoid the PRs becoming stale and requiring to be rebased on master, these can be merged
after a reasonable time (current agreement is 3 days) if the System Test Engineer Owner's sign-off
was not provided (last step in the DoD).
IMPORTANT: Any deviation from the plan should be discussed and agreed as a comment in the Feature file.
Sign-off
- Product Owner
- Dev Owner
