The _nextcloud_ role originally handled setting up the PostgreSQL database and assumed that it was running on the same server as Nextcloud itself. I have factored out those tasks into their own role, _nextcloud-db_, which can be applied to a separate host. I have also introduced some new variables (`nextcloud_db_host`, `nextcloud_db_name`, `nextcloud_db_user`, and `nextcloud_db_password`), which can be used to specify how to connect to the database, if it is hosted remotely. Since these variables are used by both the _nextcloud_ and _nextcloud-db_ roles, they are actually defined in a separate role, _nextcloud-base_, upon which both depend.
