    Use format to convert ints to strings
    
    This ensures that on 32bit architectures, where
    sometimes an implicit long is created, the resulting
    string does not contain a 'L' suffix as generated
    by the hex function.

Title:
  unit test failures on 32 bit architectures

Status in neutron:
  Fix Committed
Status in neutron package in Ubuntu:
  In Progress

Bug description:
  Test all pass fine in Ubuntu on 64 bit archs, however on a 32 bit
  architecture (which is how we build packages in 14.04), two unit tests
  fail - this is a int/long type problem.
