Auto-backup bifrost during `make status`. Gzip backups.
- Backup/Restore uses gzip (260kb to 40kb).
- Every
make status
runs a backup of Bifrost at the end. This ensures all TSS keyshares are regularly saved and THORChain achieves 2/3+ keyshares saved. - Also silences errors backing up bifrost when no JSON keyshares exist yet, e.g. before becoming active for the first time. Manual
make backup
still shows errors.
