Integration of kyberpunk/openthread in FREERTOS (openthread/ot-rtos) as a parallel to openthread/openthread

[uttaravadina]

Is your feature request related to a problem? Please describe.
Use the FREERTOS API for adding real-time capabilities to develop mqtt-sn apps on both POSIX and nrf528xx.

Describe the solution you'd like

• A setup guide with configuration and build scripts to integrate and compile.
• Wrapper APIs to utilize FREERTOS APIs for MQTT-SN APIs.
• Example apps built on FREERTOS->THREAD->MQTT-SN

Describe alternatives you've considered
null.

Additional context
Developing apps on top of FREERTOS can unpack lot of capabilities avoiding any memory and processor misuse. It will also help standardize the development for MQTT-SN apps and add any other functionalities later on.

@uttaravadina Hello. Thanks for advice. I agree that FreeRTOS provides many useful features. I also prefer using it on embedded platforms and I didn't know about this openthread project.
I will try to invest some effort to integrate it. It could be also interesting to port the client to lwIP.

You might want to look into ot-rtos as they already integrated LwIP. It can be a good reference point.
