Allow for a clock disparity on the duties endpoints (#2283)

Browse Source 
## Issue Addressed

Resolves #2280

## Proposed Changes

Allows for API consumers to call the proposer/attester duties endpoints [`MAXIMUM_GOSSIP_CLOCK_DISPARITY`](b34a79dc0b/beacon_node/beacon_chain/src/beacon_chain.rs (L99-L102)) earlier than the current epoch. For additional reasoning, see https://github.com/sigp/lighthouse/issues/2280#issuecomment-805358897.
