refactor: Service collection in command action

[tbarlow12]

• In order to allow commands to not worry about initializing the services that they need, this creates a ServiceCollection object that is injected into the command action.
• The ServiceCollection is the first param in the action call for each command
• This also allows for execution of some commands without cse.json being present
• Adds a PlaybookService interface and class, includes in the ServiceCollection

Also resolves #26
