Change functions/variables to make them aligned with context

Some functions/variables names can confuse what they really do. For ex., in pkg/utils/utils.go:

 35 // HasNetworkAttachment check if pod has Network Attachment
 36 func HasNetworkAttachment(pod *kapi.Pod) bool {
 37         return len(pod.Annotations[v1.NetworkAttachmentAnnot]) > 0
 38 }

function actually check network attachment annotations, not network attachment.

a pod is associated with a network attachment if it has a network attachment annotation. so im not sure there is an issue here.

can you elaborate on why you think there is an issue ?

Originally, You complained that name of this function a bit confusing.

[adrianchiris]

yea well, i dont remember what was confusing :)

So this should be renamed to: HasNetworkAttachmentAnnot()
