Add the capability to reset the password

• Via email or other service, developers should be able to customize/wire this
• This should be a separate optional package

Data flow:

User clicks on "forget password"
User enter its email
If the email exists, then user gets an email, with a unique link to page where the password can be updated

remember-me functionality also will be helpful.

since ZF2 used:

• https://github.com/goalio/GoalioRememberMe
• https://github.com/goalio/GoalioForgotPassword

but both also outdated
