enhance(controller): tune imagePullPolicy for worker container

[anda-ren]

Description

IfNotPresent policy is changed to 'Always'
IfNotPresent policy is not well fitted for images like ghcr.io/star-whale/starwhale:latest-cuda11.4 . The caching semantics of the underlying image provider make even imagePullPolicy: Always efficient, as long as the registry is reliably accessible. Your container runtime can notice that the image layers already exist on the node so that they don't need to be downloaded again.
