Add contracts storage list

Output should look like this: 
```
{
  “farm”: [
{“id”: XXX, version: “6.0.1”, “depoyed”: DATE, "description" : "..."},
…
],
“fomo” [
…
],
…
}
```

API (Swagger): 
* ADD(type: required, id: required, version: required, description: optional) — if “type” does not exist, it should be created
* REMOVE(id)

maybe also
* REMOVE_TYPE(type)
