These Postgres configuration variables are part of the `database.yaml` file
and don't need to be here.

This allows people to augment the Synapse image with custom tools and
addons without having to rebuild it from scratch.

If customizations are enabled, the playbook will build a new
`localhost/matrixdotorg/synapse:VERSION-customized` image
on top of the default one (`FROM matrixdotorg/synapse:VERSION`)
and with custom Dockerfile build steps.

For servers that self-build the Synapse image, the Synapse image will be
built first, before proceding to extend it the same way.

In the future, we'll also have easy to enable Dockerfile build steps
for modules that the playbook supports.

In the future, we'll also inject media storage providers that we support
into the `matrix_synapse_media_storage_providers_auto` list.

We don't like updating to untagged releases, but..

0.2.1 has some regression and upstream is not releasing 0.2.2 or 0.3.0
just yet, so we either need to downgrade to 0.2.0 or go `latest`.

We can hopefully switch back to a tagged release soon.
