Code refactoring

[coolbrg]

After going through the plugin's code a while, I think we need to do major refactoring to meet the Ruby language's style and standards.

I will be working on it after some stable release version.

Action items:

• Follow Ruby style guide throughout the plugin
• Autoload files in vagrant-service-manager.rb
• Change plugin names from Vagrant to VagrantPlugins
• YML approach for doc strings(help text)
• Service driven command structure #79 (Service driven command structure)

+1 Absolutely required. It should also take into account that the plugin in the future does not only provide commands, but also uses other Vagrant plugin mechanisms (for example action hooks).

@hferentschik : Action hook has been used for configuring providers like docker, openshift, ... on vagrant up. PR here as #54 . It would be available in next release.

Pending #54 I also think that the code in command.rb should be refactored so that the service specific bits live somewhere like lib/vagrant-service-manager/services/docker.rb. Other code like find_machine_ip can go in a common library.

If this isn't part of this PR (and I can go both ways) we need to do it ASAP.

@bexelbie lets keep it in this PR only. Will focus on refactoring after next release.
