Title:
  random.choice in /cinder/volume/utils.py may has potential security
  issue

Status in OpenStack Security Advisories:
  Won't Fix

Bug description:
  The choice is used for security here,  could we find out other more
  security methods to generate randomness?

  # NOTE(jerdfelt): Some password policies require at least one character
  # from each group of symbols, so start off with one random character
   # from each symbol group
   password = [random.choice(s) for s in symbolgroups] --------------> This line has described issue
  # If length < len(symbolgroups), the leading characters will only
   # be from the first length groups. Try our best to not be predictable
   # by shuffling and then truncating.


  
  # then fill with random characters from all symbol groups
  symbols = ''.join(symbolgroups)
   password.extend([random.choice(symbols) for _i in xrange(length)]) --------------> This line has described issue

   # finally shuffle to ensure first x characters aren't from a
   # predictable group
