RPC has a version of itself. In Neutron a plugin implements several RPC interface, so a single RPC version doesn't work. In Mixin callback class approach, RPC versioning depends on each plugin implementation and it makes harder to maintain RPC version appropriately. This patch series replaces mixin RPC callback of server side with a separate class. This commit handles server-side callback of security group RPC interface. * The server-side callback of Security group RPC is moved to api/rpc/handler and db/securitygroups_rpc_base now only contains a mixin class to add agent-based security group implementation with db operations. * get_port_from_device method in server-side callback class is moved to a mixin class of plugin implementation (SecurityGroupServerRpcMixin) because it involves DB lookup and is tightly coupled with plugin implementation rather than RPC interface definition. Most unit tests for SGServerRpcCallBackTestCase were skipped in the base class before, but now they are no longer skipped. The following items will be planned in later patches to avoid drastic changes in a single patch. * Merge security group RPC API and agent callback classes in agent/securitygroups_rpc into api/rpc/handlers/securitygroup_rpc * Remove completely duplicated db access code in get_port_from_device and get_port_and_sgs Partial-Bug: #1359416 Change-Id: Ia6535217d2e3b849a95667c1b53dd09675002892
