Consider to simplify constructor parameters

Right now the contract constructor accepts the following parameters:

kyber-pool-master-proxy-contract/contracts/KyberPoolMaster.sol

Lines 83 to 90 in 0017c68

    
           constructor( 
        
               address _kncToken, 
        
               address _kyberDAO, 
        
               address _kyberStaking, 
        
               address _kyberFeeHandler, 
        
               uint256 _epochNotice, 
        
               uint256 _delegationFee 
        
           ) public {

This method can be simplified by only using _kyberDAO for the needed addresses and calculate _kncToken, _kyberStaking, _kyberFeeHandler by calling the proper methods from KyberDAO to get the addresses information.

Here is how they are stored in KyberDAO

This change will reduce the number of addresses that the pool master needs to provide to deploy the contract and also avoid errors in setting incorrect addresses for all the contracts.

	constructor(
	address _kncToken,
	address _kyberDAO,
	address _kyberStaking,
	address _kyberFeeHandler,
	uint256 _epochNotice,
	uint256 _delegationFee
	) public {
