Feature: Improve interactions with AWS greengrass public components

[hocinehacherouf]

Is your feature request related to a problem? Please describe. Public components are retrieved and exposed by IoT Portal to allow users to affected these component to a greengrass deployment (edge model).

• Users must be able to view the recipes of these public components
• Users must be able to search public components

Describe the solution you'd like

• [ ] For each public component, IoT Portal backend must retrieve/return its recipe
• [ ] Listing of public components must use a cache/singleton, to avoid costly and unnecessary treatments
• [ ] Implement a job to refresh the cache/singleton of public components
• [ ] Implement search on aws public components on client side (server side)
