Monitor the state of the `bitwarden_rs` server process via the *processes* plugin for *collectd*.
This commit configures *bw0.pyrocufflink.blue* as a BURP client, so that the Bitwarden data can be backed up. A pre-backup script is used to take a consistent snapshot of the SQLite database before copying it to the BURP server.
*bw0.pyrocufflink.blue* runs Bitwarden_rs via Docker.
