[VOL-5358] - build & test repo using new AMI image

lf/local/include.mk
lf/onf-make/makefiles/etc/include.mk
------------------------------------
  o Include etc/features.mk early for access to macros: banner, banner-enter, banner-leave.

.gitignore
lf/local/commands/include.mk
lf/local/commands/kubectl.mk
-------------------------------------------
  o repo:voltha-openolt-adapter jobs failing due to kubectl being mia.
  o Jobs succeded by coincidence: ./kubectl or /usr/local/bin/kubectl would be used.
  o Problematic, different or stale command versions can be used.
  o Add logic to support a central installer for the kubectl command.
  o This will provide a consistent version & program behavior for the entire job run.
