The state history database is entirely too big. It takes over an hour
to create a backup of it, which usually causes BURP to time out. The
data it stores isn't particularly interesting anyway. Instead of trying
to back it up and ultimately not getting any backup at all, we'll just
skip it altogether to ensure we have a consistent backup of everything
else that is actually important.
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.
