SW-657:  Add the CEP4 optimisation target also to GNUCXX11 and move the CEP4 optimisation target to its own variants file

SW-657:  Add a new build variant for CEP4 optimisation to GNUCXX11_2018 and remove -Wno-terminate c++ option to enable warnings for throw statements in dtors

ROHD-1729: uploadMetadata: use db credentials from config file. Properly install config files for this module in CMake.

SW-657: Python programs can be started as parameter to python/python2/python3. Let SoftwareMonitor recognise them properly

SW-693: Do not depend C++ code on a pure-python package, as our CMake does not support that (well, LCS/Common does not)

SW-657: added test to prove that proton is not thread-safe. Running the PingPongTester results in eratic behaviour, either deadlocking, of crashing proton. Now let's find a solution!

SW-657: locking. logging. added test to reconnect to frombus if not receiving new jobs when the jobmanager says there are jobs to do

SW-657: added connection error handling + auto reconnect. Limited the number of threads for the buslisteners because of proton multithreading issues

SW-657: Use scu001/199 directly for LCS/Messaging/python, to avoid relying on qpid infrastructure for our services.

SW-657: a bit more logging, so we can see the autocleanupservice is listening and handling ingest notification messages

SW-657: number of threads needs to be 1 because of the way we use proton, otherswise one thread can receive a message and another thread can ack it, and then mayhem starts
