GlanceClientWrapper's onetime 'call' dosn't work with glance client V2

[Anton Arefiev]

 When we use GlanceClientWrapper's method 'call' with onetime glance V2, we can pass glance api version throw args:
def call(self, context, method, *args, **kwargs):
    version = self.version
        if version in kwargs:
            version = kwargs['version']

But condition in if statement is always false, because 'version' val stored in dict is string, and var chacked in call is None or int.

    Fix always false condition in glance wrapper

    If statement's condition in GlanceClientWrapper's method 'call'
    always false, because 'version' key passed through kwargs is
    string, and variable chacked in 'call' is None or int.
