The rbd_types package was initially created with references to the rbd
package. And the rbd package references the rbd_types package. Having
rbd/types was not possible due to recursive imports. After cleaning up
the rbd_types package, it can be renamed to rbd/types.

This commit resolves the govet issue -
`copylocks: call of append copies lock value ... contains sync.Mutex`
Embedding DoNotCopy in a struct is a convention to signal and prevent
shallow copies, as recommended in Go's best practices. This does not
rely on a language feature but is instead a special case within the vet
checker.

The only encoding version that exists is `1`. There is no need to have
multiple constants for that version across different packages. Because
there is only one version, `GenerateVolID()` does not really require it,
and it can use a default version.

this can be revisited with a cleaner solution.
