Add view to retrieve period data

[fmrsabino]

What was wrong? 👾

Closes #131

How was it fixed? 🎯

• Adds an endpoint to retrieve the activity information for a specific Campaign
• This endpoint can be used to filter the Activities done by a specific holder - by setting the holder address as the query parameter

The endpoint is as follows:

GET /api/v1/campaigns/<uuid:resource_id>/activities/?holder=<address>

{
  "count": <number>,
  "next": <url>, // nullable
  "previous": <url>,  // nullable
  "results": [
    {
      "startDate": <string>, // date string e.g.: 2024-05-20
      "endDate": <string>, // date string e.g.: 2024-05-20
      "holder": <string>, // Holder's address
      "boost": <string>, // decimal string
      "totalPoints": <string>, // big number string
      "totalBoostedPoints": <string> // decimal string
    }
  ]
}

Just minor comments.

We should return checksumed addresses.

Done in 5a58928 with gnosis.eth.django. serializers.EthereumAddressField

[moisses89]

Would we follow the same format than this serializer?

Changed in 7954e02.

Now accessing it via the source arg.

[moisses89]

We could add cache_page here to don´t hit with every request the database.
What do you think?

[fmrsabino]

Added in 5a58928.

To keep it aligned with other endpoints I kept it with the same configuration. In the future we can consider having it as an application config 👍
