Big Switch Neutron ML2 plugin integration

Add support for Big Switch Neutron ML2 plugin. Makes sure that the
package is present and sets up the [restproxy] section in ml2_conf.ini.

This also adds support for setting the ovs_use_veth option in
l3_agent.ini. There is no support for this in puppet-neutron l3 class
and it probably doesn't make sense adding it there, because this setting
isn't relevant for all l3 agent drivers, it's specific to
OVSInterfaceDriver. The ovs_use_veth option is also added to
dhcp_agent.ini.
