What's up with vouchers backup implementation status?

[doktornotor]

Ticket 351 - Vouchers backup - implemented /etc/rc.savevoucher still there
Ticket 1087 - vouchers need to save to CF periodically -> commit -> [instant revert with

@jimp:

voucher db backup already existed under a different name. Ticket is still fixed, just by different code that was already there.](https://github.com/pfsense/pfsense/commit/d12003c99517c25105673c557aebec7e3fa55dcb) Ticket 3128 - Active voucher status not restored from backup

@ermal:

Vouchers status are not backed up with the configuration as is not the user login status.

AFAICT, even with latest 2.1.1 snapshot

• the vouchers info is not saved anywhere automatically
• I cannot see any GUI place to configure this
• manually running /etc/rc.savevoucher does nothing to config.xml as far as I can tell, in fact it probably does nothing useful at all.
• and all status information is lost on reboot.

WTH is this mess?!?
