Implement neutron-ovn-vpn-agent

This patch implements vpnaas for OVN environments. It deploys
a standalone neutron-ovn-vpn-agent on neutron nodes.

The container no longer requires 'privileged: true'. Running
as the 'neutron' user with specific kernel capabilities ensures
the agent can manage network namespaces and interfaces without
full privileges.

Added capabilities:
  - NET_ADMIN       # manage interfaces, IPs, routing, firewall
  - SYS_ADMIN       # create/manage network namespaces
  - SYS_PTRACE      # allow 'ip netns exec' attach to processes
  - DAC_OVERRIDE    # bypass file read/write restrictions
  - DAC_READ_SEARCH # allow directory traversal and file read
  - SETPCAP         # retain capabilities for privileged ops

Added security options:
  - apparmor=unconfined  # disable AppArmor confinement
  - seccomp=unconfined   # disable seccomp filtering
  - label=disable        # disable SELinux/labeling

Depends-On: https://review.opendev.org/c/openstack/kolla/+/924302
