OpenCluster creates a new Cluster object for interacting with the dqlite database.

- name: Basename of the database file holding the data. Typically "db.bin". - dialer: Function used to connect to the dqlite backend via gRPC SQL. - address: Network address of this node (or empty string). - dir: Base LXD database directory (e.g. /var/lib/lxd/database) - timeout: Give up trying to open the database after this amount of time. - dump: If not nil, a copy of 2.0 db data, for migrating to 3.0.

The address and api parameters will be used to determine if the cluster database matches our version, and possibly trigger a schema update. If the schema update can't be performed right now, because some nodes are still behind, an Upgrading error is returned. Accepts a closingCtx context argument used to indicate when the daemon is shutting down.
