s3_upgrade: Update commandline options and use updated samba3 python module
upgrade_from_s3 script now requires samba3 configuration file and target directory for samba4 database. In addition, it either uses --libdir option or --testparm option to correctly guess the paths for samba3 databases (private dir and state directory). Usage: upgrade_from_s3 [options] <configuration_file> <targetdir> Input arguments are: <configuration_file> - path to existing smb.conf <targetdir> - directory in which samba4 database will be created In addition, specify either samba3 database directory (with --libdir) or samba3 testparm utility (with --testparm). Before using passdb interface, initialize s3 loadparm context using correct path settings for private dir and state directory. Export account policy from s3 to s4.
