Migrate openvswitch-switch file to avoid restarts The 16.10 release of the neutron-openvswitch charm changed the file management strategy of /etc/default/openvswitch-switch config file from managing the file when dpdk is enabled to always managing the file. Additionally, the template file was changed in the 16.10 release to modify the file header (commit 4463c334). These two changes guarantee that the contents of the file will change when upgrading the charm. The changing file contents causes the openvswitch-switch service to be restarted, which in turn causes a data plane outage. This commit fixes that by migrating the /etc/default/openvswitch-switch to be charm managed without restarting the openvswitch-switch service. The change will only attempt to migrate versions of the file which were created before 16.10 by searching for a marker in the rendered version of the file which was added in 16.10.
