[Samba] wbinfo needs a -s command similar to smbpasswd -s

[Tom Dickson]

It would be very helpful if wbinfo could take a password on STDIN in a
manner similar to the way smbpasswd -s works.

Is this feasible? Otherwise it is very hard to get a script to pass a
password like "@bob&bob *!" to wbinfo --set-auth-user=username%@bob&bob *!

Thank you.
