}

ConvertibleSpec is implemented by Spec types to allow conversion among the different versions of a given spec

Why do we need both directions of conversion?

Each version of a resource is in a different package, so the implementations of this interface will necessarily be referencing types from other packages. If we tried to use an interface with a single method, we'd inevitably end up with circular package references: 

+----------------+                    +----------------+
|       v1       |                    |       v2       |
|   PersonSpec   | --- import v2 ---> |   PersonSpec   |
|                |                    |                |
| ConvertTo()    | <--- import v1 --- | ConvertTo()    |
+----------------+                    +----------------+

Instead, we have to have support for both directions, so that we can always operate from one side of the package reference chain: 

+----------------+                    +----------------+
|       v1       |                    |       v2       |
|   PersonSpec   |                    |   PersonSpec   |
|                |                    |                |
| ConvertTo()    | --- import v2 ---> |                |
| ConvertFrom()  |                    |                |
+----------------+                    +----------------+
