EQS: Limit the block span of GetLogs RPC requests

[peekpi]

When EQS fetches contract events, it requests all events from block 0 to the latest block at once.
If the latest block number is very large or it has too many events, this request may be rejected by the node and the service will not start.
So it is recommended to start the query from the block which the contract deployed and limit the number of blocks per query.
