To workaround, CircleCI limitation [1]:
"Please note that since we do not support parallel deployment, specifying
‘parallel:true’ in the deployment phase will cause an error."
This commit moves the deployment step as the last action of the test
step. Doing so will ensure, every container will take care of pushing
images it was responsible to build.

* style: Rename TASK to STEP
* do not pull base image after it was copied from node0 and loaded.
It caused the current Dockerfile to be out-of-sync with the current image.
* do not pull images after loading the downloaded and up-to-date
base.tar. It was overwriting the base.tar downloaded and loaded.
* save debian:jessie into base.tar
* use "time" command to help identify long running operation
* rename marker file from "BASE_READY" to "BASE_AVAILABLE"
* build base image only if needed.
