wallet: adds rescan_bc option with preserving key images

- enables to perform rescan_spent / ki sync with untrusted daemon. Spent check status involves RPC calls which require trusted daemon status as it leaks information. The new call performs soft reset while preserving key images thus a sequence: refresh, ki sync / import, rescan_bc keep_ki will correctly perform spent checking without need for trusted daemon.

- useful to detect spent outputs with untrusted daemon on watch_only / multisig / hw-cold wallets after expensive key image sync.

- cli: rescan_bc keep_ki
