[DO] Licensing API

• Renamed /do/datasets to /do/subscriptions
• Added GET /do/subscription_info to get metadata from a dataset
• Added POST /do/subscriptions to enable a subscription in case of delivery time = 0 (in another case we should send an email, but we do nothing for now)
• Refactored licensing logic to a service (used now from the data_observatory.rake and the new POST endpoint)
• The new endpoints require the feature flag do-licensing

Added a minor. Quite comprehensive tests ❤️

I think we can move to acceptance (once we fix the tests)

[gonzaloriestra]

retest this please

Acceptance 🍏

• It does not work without feature flag
• It does not work without service account set up in central
• Returns dataset and geography subscription info
• It licenses a dataset if delivery time == 0 and creates the view
• It "licenses" a dataset if delivery time > 0 and does not create the view
• It lists the licensed datasets

We actually need to send the e-mail (we need it to gather metrics). I'm adding a separate issue for that.
