beacon-network: Store `HistoricalSummariesWithProof` in database instead of cache #1322

Currently, we store HistoricalSummariesWithProof in the beacon storage cache.

This is not very convenient because this content changes once per epoch and if the node goes offline for less than an epoch, it will be required to always get the latest HistoricalSummariesWithProof from the network.
