Implement a data loader

## Description
Preloading all the data will not be optimal with the magnitude of asteroids and planet data that will be loaded from the API. On a slow connection, pre-loading all this data may even exceed 3 or 5 minutes. Therefore, a dataloader factory will be created to produce the data loading mechanism to get the data from the API.

## Acceptance Criteria

- Data can be loaded on demand and when necessary
- Factory can load the data when needed
- Multiple data loaders can be created

## Implementation

- Create a DataLoader factory that has a create data loader method
- The method will accept a string input and if matched, load the requested data
- Create a PlanetDataLoader class, and give it a load method that will load the requested data from the API gateway. With the loaded data as a response invoke the create planet method with the response data provided.

> Modifications to existing implementation

- The interactor will access the repository and add the planet within
- The GetMainPlanet data will need to be renamed to CreateMainPlanet
- A Get controller action will need to exist to get the data from the API. This will have to be lightweight as possible and accesses the repository.
