Consolidate to a single tools/ow-utils docker image

Rather than defining separate images for running shell scripts,
running ansible playbooks, running gradle tasks, etc. switch
to an uber utility image that will include wsk, wsk-deploy,
and all the software packages to execute our various scripting
languages.

-Utility image for executing ansible playbooks
+Utility image for executing tasks
 ================
 
-The `ansible-runner` base image is intended to be used to execute
-utility tasks defined as ansible playbooks. The playbook to be
-executed should be mounted in the container as /task/playbook.yml by
-Kubernetes/Docker/Mesos.
+This `ow-utils` image can be used to execute various utility tasks
+for OpenWhisk using most of the tools that are used in the project.
+It includes a JDK8, python/ansible, nodejs, and standard packages
+such as bash, git, wget, curl, and docker.
 
+It also includes the `wsk` and `wskdeploy` CLIs.
