In order for GRANDPA to keep progressing it is imperative that nodes sync to all forks that are being voted on, since we cannot process a vote until we import the block it refers to (and it ancestors).
This PR adds a background worker that keeps track of the block hashes of our latest votes and re-announces them through sync when GRANDPA stops progressing. It just keeps a bounded
VecDequeof latest hashes and announces all of them when stalled, without tracking any context of round or set id.
