Add throttle limit functions.

[laurentmuller]

When the throttle_limit is shorter than the lifetime, we don't have the possibility to tell the user when he can ask for a new request.

The ResetPasswordToken use the expiresAt property for the getExpirationMessageKey and getExpirationMessageData.

We can maybe implement similar function for the throttle_limit:

• getThrottleMessageKey()
• getThrottleMessageData()
• getThrottleAtIntervalInstance()

Say that lifetime is 3600 and throttle_limit is 600. With this 2 new functions, we can use it in twig as follow:

<p>
This link will expire in {{ resetToken.expirationMessageKey|trans(resetToken.expirationMessageData, 'ResetPasswordBundle') }}.
</p>

<p>
You can only request a new password in {{ resetToken.throttleMessageKey|trans(resetToken.throttleMessageData, 'ResetPasswordBundle') }}.
</p>

We can maybe create a property to tell when user can ask for a new request:

public function getThrottleAt(): \DateTimeInterface
{
    // ...
}
