  - Improve override usability

    Currently when you deploy onap with no override file, the behavior is
    to deploy everything. In order to deploy a subset of components, an
    override file must contain all components and then disable the ones
    you don't want. As we prepare to transfer helm chart ownership to the
    teams, it will simplify the creation of project specific development
    override files, if the default behavior for deploying onap was
    reversed. Allowing override files to only contain the components
    they care to enable (and configure) and ignore the rest as they
    would be disabled by default.

    From this point on, it will be necessary to use an override file
    (as integration uses for testing) to enable all components. This
    patch includes an onap-all.yaml override file that may be used for
    this purpose.

    helm deploy dev local/onap -f onap/overrides/onap-all.yaml

    No configuration is part of this override. Its purpose is only to
    enable the components and is intended to be used in combination with
    other override files that provide environment specific configuration.
