systemvm: Fixes #2805 set gateway to empty string than None to avoid arping on 'None' (#2806)
systemvm: Fixes #2805 set gateway to empty string than None to avoid arping on 'None' (#2806)

Arping command in virtual-router was called anyway on python code.

on file: merge.py
line 239, in this code : "dp['gateway'] ='None' ''

later on CsAddress.py line 303

if 'gateway' in self.address:
self.arpPing()

This string 'None' makes if steatement always be true
the solution on #2806 makes dp['gateway'] =''

Cannot be None type because there is a string operation later on code.
