Epoch Smart Contracts

This release contains updates to many of the core contracts to support Epochs.

FlowIDTableStaking.cdc

• Verifies staking and networking keys with the cadence crypto API
• Changes reward payment to calculate rewards separately from paying them

FlowClusterQC

• See FLIP here: https://github.com/onflow/flow/blob/josh/epochflip/flips/20210322-dkg.md

FlowEpoch

• Adds the epoch contract, which acts as state machine to manage the epoch phases, including the staking auction, clusterQC, and DKG.
• See FLIP here: https://github.com/onflow/flow/blob/josh/epochflip/flips/20210607-epoch.md

FlowStakingCollection
