data_utils.rand_name() appends randam charactors with a hypen like:
def rand_name(name=''):
randbits = str(random.randint(1, 0x7fffffff))
if name:
return name + '-' + randbits
So it is not necessary to specify a hypen in caller side.
This patch adds a hacking rule for blocking "-" at the end of argument
of rand_name() calls.
