copy-from not supported for queued images

[Eoghan Glynn]

An image may be added referencing an external source via either the x-image-meta-location or x-glance-api-copy-from header.

Similarly a queued image may be associated with an external source via the x-image-meta-location header.

However a queued image may not have image content copied from an external source.

This asymmetry in respect of POST versus PUT should be fixed.

    Support copy-from for queued images.

    Fixes lp 939481

    An image may be added referencing an external source via either
    the x-image-meta-location or x-glance-api-copy-from headers.

    Similarly, a queued image may be associated with an external source
    via the x-image-meta-location header.

    However previously a queued image could not have image content copied
    from an external source via the x-glance-api-copy-from header.

    This patch addresses this asymmetry in respect of POST versus PUT.
