Image metadata button doesn't work if only one item is available

[Ivan Kolodyazhny]

If we have only one metadata item assigned, toggle button look confusing.

Steps to reproduce:
1. Open Project -> Compute -> Images panel
2. Click on 'Update Metadata' from image actions menu
3. Add one any metadata item to image and click 'Save' button
4. Expand image details clicking on '>' button

Actual: There is button ('CIM Processor Allocation Setting' in my case') which does nothing just confuses user

Expected result: if only one metadata item is assigned to an image, the button should not be clickable

I assumed this is reproducible with the master branch since the horizon version is not specified. The images panel should be under the compute panel group, not system. And I don't see the "Image Signature Verification" button. Does it need some specific configuration for the image?

[Ivan Kolodyazhny (e0ne)]

Sorry, Ying, bug description is not accurate. "Image Signature Verification" becomes visible once you sign it with Barbican. This is also reproducible with any other metadata field (if only one is assigned to image)

I am still confused about what the issue is. The patch for this seems to be something else: https://review.openstack.org/#/c/518965. Can you provide the steps to reproduce and current/expected behavior?

[Ivan Kolodyazhny (e0ne)]

I've updated bug description with steps to reproduce and current/expected behaviors. You can also see current behavior in the attached screenshot.

Thanks Ivan.

    Disable metadata switch if only one item is available

    Single metadata item on image details looks like action button,
    which is confusing, so change cursor from pointer to default.
