• sudo docker build -t $(IMAGENAME) -f docker/Dockerfile.voltha-go-controller .

Remove sudo calls from Makefile, building/testing should not require privileged access.  Sudo use will create a few problems:

• Potential failure point for jenkins.  Job automation runs in batch mode, if sudo issues a prompt instant job failure.
• Security issue / excessive scope:
  • Entire docker run, including any commands invoked from Dockerfile will be run as root.
  • If individual commands require privilege target them rather than granting wide open access.
• This also corrupts file ownership in a cloned sandbox
  • % find .git ! -user joey -ls
  • 50331976   188 rw-r----  1 root    root      190433 Apr 25 13:14 .git/index
• Which later breaks git commands that attempt to read or update index state.
