When creating the client_id for user, the library uses the device MAC.
For some of our devices WIFI isn't available and the library needs to select
a different MAC to use.
A number of IDF specific FreeRTOS API additions will be moved to
`#include "freertos/idf_additions.h". Mock tests need to include these to
properly use them as mock functions.
- New job to run host tests
- Fix leak in case of usage of interface name
- Fix host tests to expect a call to `transport_destroy` and add an
extra case
Today there is no way to add a new transport without applying
modifications to the transport list. This impose limitations on the
client usage. Adding the custom configuration we enable user defined
transports.
