configure status output.  Also updated docs.  Also added godoc url to
help text for status.

Cleanup some "go vet" and "go lint" errors.

We should automate these checks...

minikube config get/set/unset cmd

This introduces the minikube config get/set/unset command. At a basic level, it allows a more user friendly interface for setting minikube config values, but it also allows us to run validations and callbacks before and after the values have been set.

Use double brackets instead of single for boilerplate script

If you have multiple files without the boilerplate text, single
brackets won't print it out properly.

Add warning to avoid imagePullPolicy:Always.

I was previously running my development images on the GKE cluster,
so imagePullPolicy:Always was necessary.

Allow some `minikube start` flags to be set by config file

Ensures that we get the same IP between start/delete

This allows most flags for the minikube start command to be
configurable by viper as well.  If a flag is present, it will take
precedence over the value supplied in viper.

Viper doesn't handle string slices correctly (see
https://github.com/spf13/viper/issues/200) so the string slices that we
pass in as flags such as docker-env and insecure-registry are still only
handled by flags

Delete custom flag for human readable disk size

Since the value can now be passed in multiple ways (environment
variable, flag, or config file), moving the conversion out of the flag
and straight into cmd/minikube/cmd/start.go

This changes the helptext for gendocs
