/events/blocks allows the caller to query a sequence
of BlockEvents indicating which blocks were added and
removed from storage to reach the current state.
Following BlockEvents allows lightweight clients to update
their state without needing to implement their own syncing
logic (like finding the common parent in a reorg).
/events/blocks is considered an "indexer" endpoint
and Rosetta implementations are not required to complete it
to adhere to the Rosetta spec. However, any Rosetta "indexer"
MUST support this endpoint.
