Using SSH_AUTH_SOCK (ssh agent forwarding) to pull upm private repos (#124)

* using SSH_AUTH_SOCK (ssh agent forwarding) to pull upm private repos

* sshAgent as input parameter

* yarn run prettier --write "src/**/*.{js,ts}"

* yarn run lint --fix && yarn build

* reverted results-meta.ts (changed because ran prettier --check "src/**/*.js" without && eslint src)

* removed RUN apt-get update && apt-get install -y openssh-client. This change needs to be done upstream. See game-ci/docker#117
