[VOL-5358] - misc edits needed to support repo:onf-make use.

config.mk
---------
  - Simple copyright notice update.

makefiles/commands/include.mk
makefiles/commands/kubectl/include.mk
-------------------------------------y
  - Added a central installer for the kubectl command.
  - Rename commands 'help::' target to commands-help.
  - Default help is growing long in the stream.

makefiles/commands/kail/include.mk
makefiles/commands/pre-commit/
makefiles/commands/tox/tox.mk
----------------------------------
  - Update copyright notice
  - Changed default help target to target commands-help and define
    {command-name}-help for individual targets.  Default help target
    is beginning to grow long displaying everything.

makefiles/docker/include.mk
---------------------------
  - Update include docker config file (directory mount paths) to also load
    the config from lf/local/docker/config/include.mk to avoid storing
    all custom repo configs in repo:onf-make.
