HA metadata proxy PID and config files are created by root

[Rodolfo Alonso]

Both the PID and the config file for the HA metadata proxy are created by "root" user:

[root@controller-2 pids]# ll /var/lib/neutron/external/pids/
total 8
-rw-r--r--. 1 root root 7 Dec 9 19:34 deb76f07-a202-4f5d-a12f-d388f23a70db.pid.haproxy

Because of this, the deletion of those files should be done with elevated privileges.

    Both files cannot be deleted with the default permissions because
    those files are created by the "root" user.
