Refactoring Actions

[Jeff Behnke]

Because this Dashboard turned into more of a tool, there are a lot of actions that got added for various areas.
Actions

1. update
2. backup
3. install
4. migrate
   etc....
   My vision is to refactor this code so it is cleaner and more testable

 dashboard_commands
     |- commands/
          |- plugin
                |- install
                |- update
                |- get?
          |- theme
                |- install
                |- update
                |- get?
          |- host
                |- get
                |- list
          |- database
                |- backup
                |- migrate
                |- rollback

etc...
They all have various actions.
I will be committing base files to refactor-actions branch so everyone can see my goal.
Feel free to work on this but keep the work and PRs in the refactor-actions branch for now until its stable.
