Move roles/matrix* to roles/custom/matrix*
This paves the way for installing other roles into `roles/galaxy` using `ansible-galaxy`, similar to how it's done in: - https://github.com/spantaleev/gitea-docker-ansible-deploy - https://github.com/spantaleev/nextcloud-docker-ansible-deploy In the near future, we'll be removing a lot of the shared role code from here and using upstream roles for it. Some of the core `matrix-*` roles have already been extracted out into other reusable roles: - https://github.com/devture/com.devture.ansible.role.postgres - https://github.com/devture/com.devture.ansible.role.systemd_docker_base - https://github.com/devture/com.devture.ansible.role.timesync - https://github.com/devture/com.devture.ansible.role.vars_preserver - https://github.com/devture/com.devture.ansible.role.playbook_runtime_messages - https://github.com/devture/com.devture.ansible.role.playbook_help We just need to migrate to those.
