Added official S3 Storage Module for Synapse

[BackInBash]

Hey 🖖,

this is a Pull to implement the S3 storage backend as described in #176.

In order for the Plugin to work I modified the build process of the synapse container and injected the module installation. As of now its doing its thing, but uploads both to the local and the remote store. In any possible configuration.

Config Nesting from setup_install.yml into homeserver.yaml.j2 is not working as intended. Example: https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1769/files/6d305e432cae8e6d68463bcb3e13ab620e2a2aee#diff-3f01d105d3b729eb1a3cedbdc4ec41036d66dab6c4983e5464e2709a3d9ae637
