    prevent common kwargs from glance client failure

    When creating a snapshot of a server using the nova API, failure occurs
    if the image contains the metadata property "version". This was due to
    the way that the GlanceClientWrapper.call() function signature was
    structured.

    This patch forces all client positional args to be passed as a named
    "args" argument to the call() function and all client named args to be
    pass as a named "kwargs" argument to the call() function. This
    eliminates any argument name-shadowing that previously caused issues.
