delete weave-daemonset.yaml

[murali-reddy]

delete weave-daemonset.yaml which predates the manifest weave-daemonset-k8s-1.6/1.7/1.8.yaml and was used for older versions (< 1.6).

Naming is counter intuitive to think its the latest one to be updated when ever there is change is needed in the manifests.
