/**
* Minimal configuration for using mbedtls as part of mbed-client
*
* NOTE! This is an optimized, minimal configuration for mbed Client.
* We know it works with mbed Client but if you want to add more
* services/communications to the application yourself - please ensure
* you update this configuration accordingly. The default configuration
* can be found from mbedTLS Github:
*
* https://github.com/ARMmbed/mbedtls/blob/development/include/mbedtls/config.h
