casper-node-launcher-js needs to be updated for some js-client tests integration tests

@devendran-m @sacherjj the only thing I can propose right now is using docker https://hub.docker.com/repository/docker/gregoshop/casper-nctl/general

for 2.0

    - BRANCH_NODE=release-2.0.0-rc7
    - BRANCH_CLIENT=feat-track-node-2.0
    - BRANCH_SIDECAR=v1.0.1

for dev

    - BRANCH_NODE=dev
    - BRANCH_CLIENT=feat-track-node-2.0
    - BRANCH_SIDECAR=dev

those images should be hosted on Casper docker hub and not my personal docker Hub
