[4pt] Fetch rockets - Fetch data

[Rao Muhammad Akif Tufail]

Fetch data from the Rockets endpoint (https://api.spacexdata.com/v3/rockets) when the application starts (as Rockets is the default view).

Once the data are fetched, dispatch an action to store the selected data in Redux store:

• id
• name
• type
• flickr_images

NOTE: Make sure you only dispatch those actions once and do not add data to store on every re-render (i.e. when changing views / using navigation).
