Suggesting to support gpu in flavor

[QuillaChow]

Hi,
In the doc, I can see the structure of flavor

type Flavor struct {
    // The Id field contains the flavor's unique identifier.
    // For example, this identifier will be useful when specifying which hardware configuration to use for a new server instance.
    ID  string `mapstructure:"id"`

    // The Disk and RA< fields provide a measure of storage space offered by the flavor, in GB and MB, respectively.
    Disk int `mapstructure:"disk"`
    RAM  int `mapstructure:"ram"`

    // The Name field provides a human-readable moniker for the flavor.
    Name string `mapstructure:"name"`

    RxTxFactor float64 `mapstructure:"rxtx_factor"`

    // Swap indicates how much space is reserved for swap.
    // If not provided, this field will be set to 0.
    Swap int `mapstructure:"swap"`

    // VCPUs indicates how many (virtual) CPUs are available for this flavor.
    VCPUs int `mapstructure:"vcpus"`
}

I would like to manage flavor with gpu in my code, but I cannot find any field that related to this.
Can anyone tell me how to distinguish flavor with gpu in the code?
Thanks
