    _translate_from_glance() can cause an unnecessary HTTP request

    After returning from a get() call to python-glanceclient, nova runs a
    translation function on the returned Image to get the data it wants. Part of
    this process is checking for an expected set of attributes, one of which is
    the deletion time ('deleted_at'). However, if the image has not been deleted,
    deleted_at key will not exist. This forces another call to glance to occur for
    the same image. A similar problem exists for the checksum attribute, which does
    not exist before an image is active. The fix here is to only consider
    deleted_at and checksum if they are expected to be present.
