Added missing pingpong tests to cloud prod test
Cleaned up test output and inserted them into a google.visualization.Datatable object

- automates the disk partitioning described in
  https://cloud.google.com/compute/docs/disks/persistent-disks#repartitionrootpd

Removes an unnecessary semi-colon

Adding timeout for each test run so that failed tests do not block the running of the rest of the tests.

refactoring will happen when the commands are final.

roots.pem is not added to source control, but is instead saved on GCS.

The func copies roots.pem to docker host, to a location that can referenced by
Dockerfiles using the ADD directive

- the client test gets new, necessary flags

- adds a prod test command that explicitly sets the SSL_CERT_FILE to pick up
certs that the c core can load successfully.

Adding 2 runners to run the test matrix

- also corrects an error in the Go client test command

- updates grpc_update_image to install the github credential when the base
  image is built

- add rubocop as a dev dependency
- fixed many style violations it reported, often using --auto-correct
- add a rubocop config
 - .rubocop.yml shows the exceptions
 - .rubocopy_todo.yml tracks outstanding style issues
- adds a rake task to allow rubocop styling checks to be automated

- also allows it to sync multiple hosts

- adds _grpc_ensure_gcloud_ssh that creates the ~/.ssh/gcloud_compute_engine
  key file if it does not exist

- update all the grpc_** commands that use ssh to call this

Adds a command for triggering a pull of the latest built docker images.
