Make args vs. flags consistent

[tdeckers]

and add full documentation

[kenjones-cisco]

take a look at https://github.com/spf13/cobra
It handles alot of the boiler plate for creating CLIs, and it also comes with doc generation for your commands. There is a companion project https://github.com/spf13/viper for dealing with config files, etc.
