Subject: [PATCH] Add clearlinux/mixer-ci Docker Image

This patch introduces an image used for running the Mixer CI on Travis.

Previously, a very large part of the time Travis spent building and
validating Mixer PR's was spent 'swupd bundle-add'ing the packages
needed. The _mixer_ build was very short once this step was done.

This image removes the need to build and configure the image with each
Travis run; only the code needs to be copied over before the mixer
build and tests can run.

+
+This repo provides a Clear Linux* container for running the Mixer CI on Travis.
+This container has all of the packages and tools installed to build Mixer from
+source and run its test suite.
+
+# Build
+## Building Locally 
+```
+docker build -t clearlinux/mixer-ci .
+```
+> #### Note:
+> If you are behind a firewall, you may need to pass the `--network host` and/or
+> `--build-arg http://<proxy>:<port>` flags to docker build to configure your
+> proxy.
+
+## Pulling from Dockerhub
+```
+docker pull clearlinux/mixer-ci
+```
+
+# Use
+## Create a derivative Dockerfile
+This image creates a container with a user named `clr`, with the `GOPATH` in
+`/home/clr/go`.
+
+Create a `Dockerfile` based on this `mixer-ci` image. In this `Dockerfile`, copy
+the source code into the `mixer-tools` **package root** within the `GOPATH`,
+then execute the build and test steps. An example `Dockerfile` is as follows:
+```
+FROM clearlinux/mixer-ci:latest
+COPY --chown=clr:clr . /home/clr/go/src/github.com/clearlinux/mixer-tools/
+WORKDIR /home/clr/go/src/github.com/clearlinux/mixer-tools
+ENTRYPOINT ["/bin/sh", "-c", "make && sudo -E make install && make lint && make check"]
+```
+
+> #### Note:
+> You can inspect [Mixer's Dockerfile](https://github.com/clearlinux/mixer-tools/blob/master/Dockerfile)
+> to see how this is used in production.
+
+## Configure Travis to build and run the Dockerfile
+In your Travis config (`.travis.yml`), build and run your above `Dockerfile`. An
+example `.travis.yml` file is as follows:
+```
+language: go
+sudo: required
+
+go:
+    - 1.9
+
+go_import_path: github.com/clearlinux/mixer-tools
+
+services:
+    - docker
+
+before_install:
+    - docker build -t testdock .
+
+script:
+    - docker run testdock
+```
+> #### Note:
+> You can inspect [Mixer's Travis config](https://github.com/clearlinux/mixer-tools/blob/master/.travis.yml)
+> to see how this is used in production. For more information on Travis
+> configuration, see the [Travis documentation](https://docs.travis-ci.com/user/customizing-the-build).
