[VOL-5026] - Build and (pre-) deploy repo:voltha-go

Makefile
--------
  o Refactor test and mod-* targets per voltha-openolt-adatpter/Makefile.
  o Logic moved into makefiles/analysis/{coverage,sca}.mk
  o Inline ( set -euo pipefail && cmd | tee log) in test-coverage.
  o Improve error handling, "cmd | tee" will silently mask shell exit status.
  o make test failing locally (docker image: cpu profile acces denied).
  o Local problem, send a job through jenkins for accurate status.

makefiles/
----------
  o Copy in library makefiles
  o Esp docker/include.mk

compose/*/*.yaml
----------------
  o Update copyright notice

db/*/*.go
rw_core/*/*.go
--------------
  o Run gofmt -s -w on source to fix latent linting problmes that fail jobs.
