Provide a CircleCI base alpine image with all standard tools installed
We're using any of the fat-images (e.g. circleci/php:7.1-node-browsers) to run small jobs like building a docker container. These images take a long time to start up (download, extract, start).
Provide an alpine base images with all the tools installed as described in the CircleCI documentation (e.g. docker). This will
- Reduce start time
- Reduce strain on CircleCI infrastructure
