Subject: [PATCH] Add .pipeline/ with dev image variant

This adds a .pipeline/, containing:

  - blubber.yaml which, for now, defines a single variant for creating
    a Docker image to be used by the local-charts[0] environment.  This
    image is built on dev-stretch-php72-fpm-apache2, which is defined in
    dev-images[1].

  - dev_prereq.sh which installs some extensions, runs composer, and
    creates a stub LocalSettings.php in the dev image as a blubber builder
    command.

  - config.yaml for building the dev image.

This depends on publication of dev/stretch-php72-fpm-apache2 to
docker-registry.wikimedia.org:

  - https://phabricator.wikimedia.org/T223327
  - https://phabricator.wikimedia.org/T223329

It can be tested locally by:

  1. Installing Docker, blubber[2], and Minikube

  2. Building the images in dev-images with `make`

  3. Saving a copy of the dev-stretch-php72-fpm-apache2 image:

     $ docker save -o dev-stretch-php72-fpm-apache2.tar
       docker-registry.wikimedia.org/dev/dev-stretch-php72-fpm-apache2

  4. Importing that image into Minikube's docker:

     $ eval $(minikube docker-env)
     $ docker load --input ./dev-stretch-php72-fpm-apache2.tar

  5. Building an image tagged "docker-registry.wikimedia.org/dev/mediawiki"
     from the root of this repository:

     $ blubber .pipeline/blubber.yaml dev | docker build --pull=false -t docker-registry.wikimedia.org/dev/mediawiki -f - .

That image should now be usable by local-charts.
