Test runner - test() async support

[0xc0170]

The code reference for what I understand is the test runner which expects the result to be returned from a test():

htrun/mbed_host_tests/__init__.py

Line 410 in a8435d2

def execute(self):

Shall we consider async support for our test cases (for host tests)? This might be useful to write async host test, which would be terminated once {{end}} is received.

For instance, client has 2 test cases, which send data. Host test echoes them back. Once client is done and the tests passes, sends {{end}}, this would terminate host test() method, call teardown().

The code which we wrote was referenced here : ARMmbed/greentea#50 (it's not quite correct but illustrates a user case for having async host test).

This will be covered by this breaking change: ARMmbed/greentea#78

I will close this because we will continue in separate threads.
