Microsoft.Framework.Expiration.Interfaces namespace has just one type

The Microsoft.Framework.Expiration.Interfaces namespace has just one type: IExpirationTrigger

https://github.com/aspnet/Caching/blob/dev/src/Microsoft.Framework.Caching.Abstractions/IExpirationTrigger.cs#L6

And what a weird namespace name, too.

it appears to be used within caching, and also within the FileSystem repo to implement the file watcher notifications, e.g.:

• NoopTrigger
• IFileProvider

I don't have a specific suggestion on what it should be, but I don't think it can stay as is. Perhaps it goes to the main Caching namespace? (And we get rid of the unnecessary .Interfaces namespace suffix as well.)

Agreed, this interface should stay in Abstractions assembly, and the namespace should be Microsoft.Framework.Caching
