* Updated Azure CLI image name, map .azure folder from host file system, fix block running on Windowns containers, fix Windows path issues (this didn't make it into `0.0.12`)
* Added telemetry to understand which commands developers find useful. This will help us refine which commands we add in the future. We track whether the following commands are executed:
*`open shell` on running container and whether or not it is a Windows or Linux based container
*`push image` (we don't track the image name or the location)
*`remove image`
*`show logs`
*`start container`, `start container interactive`
*`start Azure CLI` container
*`stop container`
*`system prune`
*`tag` (we don't track tag name)
* Configure workspace along with the type (e.g. Node or Other)
> Please note, you can turn off telemetry reporting for VS Code and all extensions through the ["telemetry.enableTelemetry": false setting](https://code.visualstudio.com/docs/supporting/faq#_how-to-disable-telemetry-reporting).
* Removed `MAINTAINER` from templates and linting warnings by upgrading the `dockerfile_lint` module (Docker has deprecated `MAINTAINER` in favor of `LABEL`).
* Added command to run `docker system prune`, note we use the `-f` (force) flag to ignore the confirmation prompt.
*`Docker: Attach Shell` command now supports Windows containers [#58](https://github.com/microsoft/vscode-docker/pull/58).
