1199 eth syncing

[olehnikolaiev]

fixes #1199

tested manually on devnet as following:

• run load test
• turn off one of the nodes
• wait for 1 hour
• turn the node back on. the node should catchup the missing blocks
• check eth_syncing(). it should return something like

> eth.syncing
{
  currentBlock: 158312,
  healedBytecodeBytes: 0,
  healedBytecodes: 0,
  healedTrienodeBytes: 0,
  healedTrienodes: 0,
  healingBytecode: 0,
  healingTrienodes: 0,
  highestBlock: 159200,
  startingBlock: 156449,
  syncedAccountBytes: 0,
  syncedAccounts: 0,
  syncedBytecodeBytes: 0,
  syncedBytecodes: 0,
  syncedStorage: 0,
  syncedStorageBytes: 0
}

via geth or

{"id":73,"jsonrpc":"2.0","result":{"currentBlock":165382,"highestBlock":167451,"startingBlock":165145}}

via json-rpc during catchup and

> eth.syncing
false

via geth or

{"id":73,"jsonrpc":"2.0","result":false}

via json-rpc when catchup is finished.
