dependency management about vflow

[mmlb]

@mehrdadrad can you expand on why you think it is not necessary? If I build vflow today I have no guarantees that when I go to build it next month that it will build again. Both sarama-cluster and gopkg.in/yaml are at major version 2 which is evidence of this happening once before and possible in the future.

@mmlb pls post more details about this.

I'm not sure what else to post apart from "vflow should be managing it's dependencies", here's dep init output:

I'd be happy to sumbit a PR to add dep metadata files and make use of it in the makefile/dockerfile, I wanted to gauge if this was something that would be wanted.

@mmlb it's not necessary, thanks!
