Allow DisplayAttribute on Class declarations

[cervengoc]

Hello, I'd like you to consider allowing DisplayAttribute on class declarations. Forgive me if this is a duplicate, I haven't found anything related. Some use cases for it:

• Auto-generate form captions
• Auto-generate report captions
• Use this information to extend nested property captions (like Person.Details.Address could get a label as Personal info / Address)
• Auto-generate documentation (consuming Description and Order for example)
• etc.

Data Annotations Triage: This seems to be a reasonable request. We are not planning to work on it for the time being but we would consider a PR. It is likely that changes would be needed on frameworks that use data annotations such as ASP.NET Core MVC (maintained at http://github.com/aspnet/mvc/) in order for it to work end-to-end.

@divega, I'm interested in working on it. Can I PR the DisplayAttribute class changes and if accepted submit an issue on ASP.NET Core MVC repo?

@brunolins16 I sent you collaborator invite, so that we can assign the issue to you. Ping me once you accept the invitation and I will assign the issue to you. Assigning to myself temporarily.
Note: Being collaborator will automatically make you watch the entire repo (500+ notifications per day). I would recommend to change it to "Not Watching" to get only mentions.

Just curious, how do changes like this to the .NET Core API flow back into the .NET framework? Can I expect this change to be included in .NET Framework vNext as well? This issue is forcing me to use a rather nasty kludge at the moment for required functionality of a library.
