feat(spec): adding v1 CRD for ZFS-LocalPV

[pawanpraka1]

fixes: #87

What this PR does?:

Moving the CRDs to stable v1 version.

Upgrade:

When an object is written, it is persisted at the version designated as the storage version at the time of the write. If the storage version changes, existing objects are never converted automatically. However, newly-created or updated objects are written at the new storage version. It is possible for an object to have been written at a version that is no longer served.

When you read an object, you specify the version as part of the path. If you specify a version that is different from the object’s persisted version, Kubernetes returns the object to you at the version you requested, but the persisted object is neither changed on disk, nor converted in any way (other than changing the apiVersion string) while serving the request. You can request an object at any version that is currently served.

If you update an existing object, it is rewritten at the version that is currently the storage version. This is the only way that objects can change from one version to another.

Here, made v1 as the storage version. And we can still query the v1alpha1 CRDs via v1 version. Since schema is same for both, using conversion strategy as none.
