Debian and RPM package feature request.

[vijaysar]

First of all for this good framework and nice software to get IPFIX data into big data like systems in a native and simple way. These are more feature requests I have to help see this in a production system at an ISP. My desire is to use these to create tools for DDOS early warning, malware detection like use cases. Here are the feature requests

1. vflow_stress links to a file that is local or ssystem specific
2. vflow running as a non root user.

1: vflow_stress problem
vflow_stress from rpm or debian seems to be linked to a GOPATH or package and cannot execute without a specific link to this file, see error below:

I can fake it to run but this will be a good one to fix.

2: vflow as a non-root user

The directories /usr/local/vflow and /var/log/vflow can all be owned by a user called "vflow" - in most systems that I manage we try to minimize things running as root, so it can be good to create a "vflow" user and chown the files and pid directories to be all with "vflow" user.
