Eden as library: Refactoring stage 2

[uncleDecart]

What:

In previous PR #803 we swept all global variables in mediator it does not solve the problem of confusing, but it enables easier refactor, which does not require rewriting whole application. We need to prune Runtime arguments which were added to config structure, remove as maximum as possible.

How:

We can use local variable reference (since we’re using Golang and we have garbage collector, we can do it). Example you can see below via configName variable

func NewRootCommand() *cobra.Command {
	var configName string

	rootCmd := &cobra.Command{
		Use: "root",
	}

	groups := CommandGroups{
		{
			Message: "Basic Commands",
			Commands: []*cobra.Command{
				newSetupCommand(&configName),
			},
		},
	}

	groups.AddTo(rootCmd)

	rootCmd.PersistentFlags().StringVar(&configName, "config", "test", "Name of config")

	return rootCmd
}

Outcome:

Fixed API, we can branch out eden and start developing on top of it (network configuration, testing framework, benchmarking framework)
