    Fix monasca-grafana being unbuildable due to old npm

    Affected builds on Ubuntu which had:
    npm 3.5.2
    while the latest was:
    npm 6.13.4
    And CentOS had:
    npm 5.6.0

    This patch runs npm update via npm.
    Pinned to 6.x.

    Additionally, this moves npm packages prefix (root) to
    /usr/local to avoid conflicts with native packages.
