Allow customers to add custom password rules to their GateIn installations.
We've had a discussion about the possibilities, and it seems that the best for now would be something as follows:
1) Adapt/extend the current UserConfigurableValidator, which allows the usage of min/max/regex constraints for values based on values from a configuration file, for instance:
2) Extend the User Interface to allow the administrator to enter the name of the configuration entry related to the password policy (mycompanypasspolicy , in this case).
