Refactor the test_qos.QoSTestMixin._check_bw function
Improved the robustness of this function:
- The remote process ("nc"), will be stopped both at the beginning and
the end of this function, just to ensure the process is not left
running at the beginning of the next check.
- The socket connection is closed when the file is received (or in case
of exception). This will close the client socket and will end the "nc"
process in the remote VM.
- Set a socket timeout. This timeout, specifically defined for each
iteration, depending on the expected bandwidth, will force a quick
timeout while receiving from the remote VM. The check will fail and it
will be tested again, if the "FILE_DOWNLOAD_TIMEOUT" didn't happen yet.
