SEC-2428: support "last password change date" in the DB schema

I would like to support the feature that after the user logs-in, I can tell if it is time for him to change his password. For this, I need to add in the DB, better in the 'users' schema, another column of DATE, that indicates the last time this user has set his password.
Currently, if I work with Spring-security, and I use the current 'users' schema, I cannot support this feature.
BTW, this way developers will be able to use UserDetails.isAccountExpired(), which is currently useless. Or maybe we can add another method for this use-case...

changes required:

1. new column in the DB, 'LAST_PASSWORD_CHANGE_DATE'.
2. JdbcUserDetailsManager:
   2.a the queries (for create account, for example) will have to change.
   2.b. changePassword(): it will have to set a new value in the 'LAST_PASSWORD_CHANGE_DATE'.
3. interface 'UserDetails' and implelemtor 'User' will have to change accordingly.

Start by inspecting the current users schema and the JdbcUserDetailsManager, then trace the UserDetails interface and User implementation. Update the account-creation queries and changePassword() behavior around LAST_PASSWORD_CHANGE_DATE, and define the corresponding user API so the password-change date can be used after login.
