Update server with nri injection points

Browse Source 
This allows development with container to be done for NRI without the need for
custom builds.

This is an experimental feature and is not enabled unless a user has a global
`/etc/nri/conf.json` config setup with plugins on the system.  No NRI code will
be executed if this config file does not exist.
