modules: HACK link lua_modules to modules

temporary hack so that luvit can find the virgo modules. We need to move
everything in lua_modules to modules to remove this hack (separate PR)
monitoring: tests: add fixtures server

The fixture server is a simple tls server written to be ran under luvit
that serves up fixtures from the fixtures directory and periodically
sends a schedule changed event.
monitoring: introduce --insecure flag

The monitoring fixtures server uses the insecure CA cert from luvit.
Make the agent use this insecure CA when --insecure is passed into it so
that it will connect.

This requires passing an options object all the way through the code
from MonitoringAgent.run() through to the AgentClient class.

Also introduce changes to tools/build.py so that the server and agent
can be ran as so:

     python agents/monitoring/runner server_fixture
     python agents/monitoring/runner endpoint_fixture
