s3:secrets: add infrastructure to use secrets_domain_infoB to store credentials
We now store various hashed keys at change time and maintain a lot of details
that will help debugging failed password changes.
We keep storing the legacy values:
SECRETS/SID/
SECRETS/DOMGUID/
SECRETS/MACHINE_LAST_CHANGE_TIME/
SECRETS/MACHINE_PASSWORD/
SECRETS/MACHINE_PASSWORD.PREV/
SECRETS/SALTING_PRINCIPAL/DES/
This allows downgrades to older Samba versions.
