Problem

We are unable to spin up clusters where the vote_state_v4 feature flag is not active (e.g. cluster_type == MainnetBeta)

To repro: solana-test-validator --deactivate-feature Gx4XFcrVMt4HUvPzTpTSVkdDVgcDSjKhDN1RqRS6KDuZ - no slots will be finalized.

We've seen similar reports from users running local clusters (e.g. fd / jito)

Proposed Solution

We should feature gate initial vote account creation to create v3 accounts if the feature is not active
