This reworkds --recovery-pin= from a parameter that takes a boolean to an enum supporting one of "hide", "show", "query". If "hide" (default behaviour) we'll generate a recovery pin automatically, but never show it, and thus just seal it and good. If "show" we'll generate a recovery pin automatically, but display it in the output, so the user can write it down. If "query" we'll ask the user for a recovery pin, and not automatically generate any. For compatibility the old boolean behaviour is kept. With this you can now do "systemd-pcrlock make-policy --recovery-pin=show" to set up the first policy, write down the recovery PIN. Later, if the PCR prediction didn't work out one day you can then do "systemd-pcrlock make-policy --recovery-pin=query" and enter the recovery key and write a new policy.
