Fixes https://github.com/paritytech/polkadot-sdk/issues/3144 Builds on top of https://github.com/paritytech/polkadot-sdk/pull/3229 ### Summary Some preparations for Runtime to support elastic scaling, guarded by config node features bit `FeatureIndex::ElasticScalingMVP`. This PR introduces a per-candidate `CoreIndex` but does it in a hacky way to avoid changing `CandidateCommitments`, `CandidateReceipts` primitives and networking protocols. #### Including `CoreIndex` in `BackedCandidate` If the `ElasticScalingMVP` feature bit is enabled then `BackedCandidate::validator_indices` is extended by 8 bits. The value stored in these bits represents the assumed core index for the candidate. It is temporary solution which works by creating a mapping from `BackedCandidate` to `CoreIndex` by assuming the `CoreIndex` can be discovered by checking in which validator group the validator that signed the statement is. TODO: - [x] fix tests - [x] add new tests - [x] Bump runtime API for Kusama, so we have that node features thing! -> https://github.com/polkadot-fellows/runtimes/pull/194 --------- Signed-off-by: Andrei Sandu <andrei-mihail@parity.io> Signed-off-by: alindima <alin@parity.io> Co-authored-by: alindima <alin@parity.io>
