For Infura, topic filter API is not available, so only eth_getlogs can be used for polling

For local node, use eth_newfilter and eth_getFilterChanged.
web3j implements filter polling in this way (ethLogObservable)

Will not use eth_newfilter and eth_getFilterChanged, because I want to keep sync states for ether and tokens the same.
So, for syncing of a block:

  1. Use eth_getBlockByNumber to sync ether txs
  2. Use eth_getLogs to sync token txs
