cfy_manager start/stop fails if service not installed, for example in community edition, start/stop will fail with following error:
2018-03-11 15:28:26,566 - [MAIN] - ERROR - BootstrapError: Failed running command: sudo systemctl start cloudify-composer (Failed to start cloudify-composer.service: Unit not found.).
2018-03-11 15:27:51,757 - [MAIN] - ERROR - BootstrapError: Failed running command: sudo systemctl stop cloudify-composer (Failed to stop cloudify-composer.service: Unit cloudify-composer.service not loaded.).
similarily, if influxdb or riemann are not installed on the manager.
1. use cloudify manager community edition
2. run cfy_manager start/stop
