Update git submodules

* Update docs/submodules/ccsdk/cds.git from branch 'master'
  to dfe5205bf91864febb2a69d33ede23f3824bb9ed
  - Added npmVersion to install NPM

    To install local copy of npm, needed to make 2 changes to
    frontend-maven-plugin configuration:

    1) Add tag <npmVersion>6.4.1</npmVersion>
    2) Removed tag <npmDownloadRoot>

    Confirmed in local build that those changes result in npm being installed
    in local 'node' directory (which it was not before these changes).

    Also, changed parent version to 1.3.1-SNAPSHOT - this will be needed to
    prevent builds from breaking when new SAN certs are installed for ONAP gerrit.
