Clean up unnecessary k8s object information

[Jeffwan]

Currently, entire pod detail is printed out.

aws-fargate/provider.go

Line 111 in 3508966

log.Printf("Received CreatePod request for %+v.\n", pod)

aws-fargate/provider.go

Line 230 in 3508966

log.Printf("Responding to GetPods: %+v.\n", result)

This makes virtual kubelet fargate provider logs kind of messy. Technically we don't need that many information since these can be retrieved from k8s. Only namespace/name is good enough. I will do some improvements to remove some unnecessary logs.
