This patch changes v3 security_groups API to v2.1 and makes v2 unit tests share between v2 and v2.1. This patch doesn't revert /os-security-groups, /os-security-group-rules and /servers/server_id/os-security-groups because these features are implemented in Networking API. On v2.1 API, we decide we don't need to implement proxying features. The differences between v2 and v3 are described on the wiki page https://wiki.openstack.org/wiki/NovaAPIv2tov3 . Partially implements blueprint v2-on-v3-api Change-Id: I82660fd514d041bdd1fad0e689fa4fe90d441c47
