Currently, the Cisco VPN drivers use two routers for the proof of concept solution. A Neutron router provides access to the public and private subnets, and a Cisco CSR (out-of-band) provides the VPN tunneling. The end goal is to integrate the Cisco VPN drivers with the Cisco L3 routing plugin being developed (as a separate blueprint), allowing an in-band CSR to be used as a Neutron router for VPN functionality. This commit provides an incremental approach to that goal, by modifying the Cisco VPN drivers to be able to dynamically obtain CSR info from an INI file, instead of statically reading the INI file at start-up. A CSR VM can be created out-of-band (or in-band using Nova) and the INI file can be updated with the router info. Then, the Cisco VPN driver can use that information (dynamically) to create IPSec connections. Once the Cisco L3 router plugin is available, the INI file will be removed, and two calls to the plugin will be used to obtain the needed router information, for an integrated solution. The main advantages are: - Dynamically use the CSR for VPN. - Less manual intervention and setup. - Easy migration to final solution. - No dependency on the Cisco L3 router plugin implementation. Note 1: The INI unit tests are moved from device driver to service driver and modified. Note 2: I added a unit test for deleting IPSec site-to-site connection, which was missing (pass).
