Minimize external user registration link expiration duration

Manage the number of days that a registration link can be accessed.

If the sn_ext_usr_reg.Reg_link_expiration_days system property is not set to the recommended value of 3, then a registration link could be used by someone other than the intended user if the link is discovered later in time.

Ensure that the property sn_ext_usr_reg.Reg_link_expiration_days is set to 3 or less.
