Task auto-conversion from v1alpha1 to v1alpha2 🎋
This adds auto-conversion methods and tests for Task types in v1alpha1 and v1alpha2. In order to reduce the number of duplicated fields, we are using v1alpha2.TaskSpec embedded in v1alpha1.TaskSpec so that both types are compatible. Signed-off-by: Vincent Demeester <[email protected]>
