chanbackup/[feature]: add archive mode for channel back ups

Roasbeef commented 4 months ago

Is your feature request related to a problem? Please describe.

To ensure that certain classes of recovery are always possible, we should considering adding a mode to never delete channel backups, and only rename or move them to a special folder that stores archived chanenls. They're relatively small (~300 bytes or so), so it shouldn't take up a significant amount of disk space.

Describe the solution you'd like

Implement the above behavior by default, adding a flag to optionally disable it.

Describe alternatives you've considered

Users can also use the various notify scripts to always grab and archive the backups themselves. This requires extra software.
