Lucas Alvares Gomes 5f26dda1e6 Add privsep rootwrap configuration support and filters
This patch adds the ability to configure rootwrap for ovn-bgp-agent. It
creates the entrypoints, configuration variables as well as some sample
configurations under etc/ that will be later used by DevStack to
configure the environment.
