Wenzhi Yu 96bd39afad Enable etcd DB backend testing pipeline ... As disussed in project plan, we decided to adopt etcd to store container data which is faster and more flexible than mysql. This commit enable etcd DB backend testing pipeline in Zun and adjust the code correspondingly: 1. Set the value of 'db_type' to 'etcd' when runing etcd pipeline: 'gate-zun-devstack-dsvm-docker-etcd-nv'. 2. Drop the 'get_XXX_by_id' methods from etcd API since 'id' attribute makes no sense in etcd data model. 3. Adjust DB related test cases. 4. Make etcd write request thead-safe. After the etcd related code been well tested, we'll change the default DB type from 'mysql' to 'etcd'.
