Fix soft stop and start of engine
Stopping an apexc engine is a soft stop, allowing the engine to be restarted again. However, when a model upgrade is carried out the engine must be stopped and cleared to clear the previous model, loaded with the new model and started again. THis handling must work over the Web Socket admin interface and also when apex is started as a service. This change fixes the handling so that it is consistent and works the same when apex is stopped/started/upgraded from the command line or over the management web socket interface Issue-ID: POLICY-1101 Change-Id: I1fe619641cb6ecd34d0669b4b7df105280e5e2c0 Signed-off-by: liamfallon <liam.fallon@ericsson.com>
