Changing the Generation and ObservedGeneration

Removing generation and observed generation from Image Spec and Status.
Adding new Regeneration field in the Spec which will be used for kicking
off a new round of reconciliation.
If the image status is "does not exists, the reconcilaition can be re-triggered, even if
no objects monitored by the reconciler have been changed (image pushed
to repo, Build/Sign dockerfile changed, etc')
