Changing api version in generate command since it was
outdated v1alpha2. The following changes took place:
* duplicated v1alpha2 package to v1 to avoid confusion
* updated examples to point to the right version
* updated default value to be v1 instead of v1alpha2
* fixed a bug where default namespace is unset
