Add contrail-tor-agent to ModuleIds in vns.sandesh

REST API /analytics/send-tracebuffer/<source>/<module>/<instance_id>/<name>
fails if the contrail-tor-agent is specified for <module>.
Check for <module> fails in contrail-analytics-api as contrail-tor-agent
is not added in the ModuleIds in vns.sandesh
