flavor metadata does not include extra specs

[Mounika]

I'm using stable mitaka openstack.
Flavor metadata do not include extra specs of the flavor.

Steps to reproduce
1. Upload a hot template with flavor which has extra specs
2. launch stack
3. Click on resources tab
4. click on flavor

The extra specs which where provided while launching the stack are not visible in resource (in this case flavor)metadata.

Expected result:
Extra specs which were provided during launch stack should be visible in resource metadata

Please find the screenshot attached below for reference.

The heat panels predate extra-specs. So it makes sense that they might not have been updated to show this new data. Marking as wishlist. Just need someone to update the panel.

heat panel is split out to heat-dashboard. Retargeting to heat-dashboard.

I think stack resource metadata is corresponding to the physical resource property 'metadata', as
```
type: OS::Nova::Server
    properties:
        metadata: {}
```
Heat dashboard may show the resource (flavor in this case) extra_specs property in a new 'Extra specs'. Or, we can simply merge extra_specs into `Resource Metadata` already on the resource detail page.

I think that the resource metadata field what you guys are talking is a entity within Heat, should not have the resource specific attribute like as extra_spec of flavor.
