  o Add exclusion lf/onf-make for repo:onf-make git submodule.
  o Add exclusion for .tmp (makefiles/nvm/nvm.mk)

makefiles/lint/groovy/groovy.mk
makefiles/lint/groovy/include.mk
makefiles/lint/groovy/install.mk
--------------------------------
  o Update targets to latest lint-{language}-{all,mod,src} syntax.
  o Installer updated to depend on npm/nvm.mk target 'npm-groovy-install'.

makefiles/lint/make/makefile.mk
makefiles/lint/json.mk
makefiles/lint/python/flake8.mk
makefiles/lint/shell/shellcheck.mk
makefiles/lint/yaml.mk
------------------------
  o Simplify find command exclusions.
  o Use "-not -path [p]" in place of "( -name p ) -prune".

makefiles/main/tempdir/tempdir.mk
---------------------------------
  o Fixed a typo $(HELP) -> $(HIDE)

makefiles/lint/doc8/doc8.ini
-------------------------------
  o Add directory exclusions from onf-excl-dir=.
  o Remove txt from the list of file extensions to check
    repo:voltha-docs is the only repo with *.txt files that contain
    restructuredText so add the extension in the local per-repository
    config.
