OSpurge fails on ressources with non-ascii caracters

[Zarrouk Mohamed]

If a ressource has a non-ascii name (chineese name: 华为技术公司), ospurge faills with following traceback (for this example i created a network with the chineese name):
* Resources type: NeutronNetworks
Traceback (most recent call last):

    Use unicode formatting

    The openstack clients return unicode strings as ressource names.
    In python2.7, we need to use unicode encoding when dealing with string
    formatting otherwise it is treated as python2 str and we try to cast
    a unicode string into an str.
    In python 3 prefixing a string with u has no effect and is supported
    and considered as a python3 str which are natively unicode strings.
