Campaigns objectives endpoint

[irfano]

Part of: #12469

Description

This adds functions to the BlazeRepository for fetching campaign objectives.
I haven't included unit tests since the newly added functions don't have complex logic and act as a gateway to the FluxC library.

Warning

do not merge: FluxC reference should be updated to the trunk hash before merging.
Known issue: Although the campaigns/objectives endpoint accepts a locale parameter, the response is not localized on the API side.

Steps to reproduce

Fetching objectives is not yet implemented in the UI. The retrieved data can only be viewed using the Database Inspector. To fetch objectives on the Blaze campaign preview screen, apply this patch: Fetch_objectives.patch

1. Apply the patch.
2. Build the app.
3. Tap the "Create campaign" button on the My Store tab.
4. Select a product.
5. Open the Database Inspector.

Testing information

The data in the Database inspector should be like this:

The tests that have been performed

I verified the stored data in the BlazeCampaignObjectives table.
