  - Add Makefile option to skip lining of helm charts

    For some reason after introducing our awesome templates to ONAP make
    command can take now quite a lot of time, which sometimes causes out
    CI jobs to fail.

    Command that takes so much time is helm lint.
    This patch adds a Makefile option that allows you to skip linting of
    helm charts and just build them. Example:

    make SKIP_LINT=TRUE

    Default behavior stays unchanged.
