CFY-750 added error codes to REST service; refactored error handling
CFY-731 added calls to monitor lifecycle's start and stop to the default install and uninstall workflows respectively; added integration tests for these calls; added a few sleep(5) calls in uninstall integration tests to allow elasticsearch to update execution status and avoid sporadic failures

CFY-731 modified default install/uninstall workflows: task flow is no longer dependent on start/stop monitor tasks; stop monitor task now has an 'ignore' error handler; changed the way we test for stop-monitor call in test_uninstall_deployment (since the order of stop-monitor calls of dependent nodes is no longer necessarily guaranteed)
