Fix memory plugin build

easyjson does not work with main packages. Workaround changing the
package name as suggested in mailru/easyjson#236

Some code has been moved from skydive to graffity: common.Getter

Clean and update gomod:
k8s deps should be added with replace, kubernetes/kubernetes#79384
Same problem with networkservicemesh
viper is not being used
add skydive as dep, not local replace

Once compiled it fails to run with skydive because problems with the Go
plugin framework.
The error is: plugin was built with a different version of package golang.org/x/sys/unix

golang/go#20481
golang/go#27751

Tested adding to the skydive.yml config file:
plugin:
  plugins_dir: /home/adrian/go/src/github.com/skydive-project/skydive-plugins/memory
  topology:
    probes: memory
