FreeRTOS+TCP 4.0.0 What is the "proper" way to change end-point settings

Thanks @epopov for the the question and feedback.

For v4.0.0, It is best to use FreeRTOS_FillEndPoint(). An example is provided in our IPv6 demo

FreeRTOS_FillEndPoint() sets the ipv4_defaults, which will be used if DHCP fails (see here).

I can’t recall if there is a case for FreeRTOS_SetEndPointConfiguration(). I see there was a similar thread earlier for FreeRTOS_SetAddressConfiguration()

@Shub @htibosch @moninom1 @tony-josi-aws @ActoryOu → Thoughts ?

Either way, I think there is scope for updating documentation here.
