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.

vijay@linux: vflow_stress panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x78 pc=0x4a490e]

goroutine 4 [running]: main.main.func1(0xc420010590, 0xc4200105a0, 0x10, 0x10) /root/go/src/github.com/VerizonDigital/vflow/stress/stress.go:73 +0x7e created by main.main /root/go/src/github.com/VerizonDigital/vflow/stress/stress.go:80 +0xcc

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.
