Do we really ned to vendor golang ?

[qinqon]

What happened:
Now we use install-go.sh to vendor golang version from the version at go.mod

What you expected to happen:
So project is stick with the version there.

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:
Thing is we may not need it, since it looks like go compiler do a switch back to lang version
specified at go.mod [1] [2] [3].

Let's check if compiling failes if we add 1.13 errors Wrapf and build with golang 1.13.

[1] golang/go#30603
[2] https://golang.org/cmd/go/#hdr-The_go_mod_file
[3] golang/go#28221

Environment:

• NodeNetworkState on affected nodes (use kubectl get nodenetworkstate <node_name> -o yaml):
• Problematic NodeNetworkConfigurationPolicy:
• kubernetes-nmstate image (use kubectl get pods --all-namespaces -l app=kubernetes-nmstate -o jsonpath='{.items[0].spec.containers[0].image}'):
• NetworkManager version (use nmcli --version)
• Kubernetes version (use kubectl version):
• OS (e.g. from /etc/os-release):
• Others:
