Lujin Luo 6281fddbcb Add a unique key to port_id in routerports table ... If multiple commands to add router interfaces to different routers by the same port are executed concurrently, then all the commands would show success. However, there are three issues: 1. Only one router interface is actually added by the port 2. Multiple router ports records are stored in routerports table 3. The port table is updated multiple times and eventually the last-arrived command would truly take effect This patch adds a unique key to port_id in routerport table, so that only the first-arrived command will insert router port record and all later requests would raise exceptions. Besides, port.device_id and port.device_owner in port table needs to be updated again after routerport record is inserted. Otherwise, in race condition the port table will store the router information from last-arrived request. However, in routerport table, only the first-arrived request's router information is inserted.
