config/generator.py crashes when no help in conf

[Thomas Goirand]

When there is no help for a configuration object, config/generator.py crashes with the below stack dump:

WARNING: "auth_admin_prefix" is missing help string.
Traceback (most recent call last):
  File "./tools/conf/../../ceilometer/openstack/common/config/generator.py", line 255, in <module>
    main()
  File "./tools/conf/../../ceilometer/openstack/common/config/generator.py", line 252, in main
    generate(sys.argv[1:])
  File "./tools/conf/../../ceilometer/openstack/common/config/generator.py", line 98, in generate

    _print_opt(opt)

    opt_help += ' (' + OPT_TYPES[opt_type] + ')'
TypeError: unsupported operand type(s) for +=: 'NoneType' and 'str'

I'll be fixing this.

    When there is no help available for an option, the generator.py
    simply crashes. This fixes this by initialising opt_help.
