Always commit after deployment db operations
This should eliminate a potential race where a depolyment create doesn't get commited before another engine calls SoftwareConfigService._refresh_software_deployment This change also adds a functional test which creates 4 parallel deployments to a server and assert that all 4 end up in the server metadata.
