feat(groupmodels): add possibility to set up group models with metadatas

[QuentinRousselet]

What does this PR do ?

This PR adds the possibility to create group models fro asset groups and define metadatas, metadataDetails, defaultValues and tooltipModels.

How should this be manually tested?

• Step 1 : Create a group model with metadatas and default values using the api/action
  { "controller": "device-manager/models", "action": "writeGroup", }
• Step 2 : Create an assetGroup specifying the model you previously created
• Step 3 : Verify that the default values for metadatas have been created
• Step 4 : Update the assetGroup and try changing the value of the metadataFields
