Add Admin API Endpoint to Enable Provider/Source

[adberglund]

User Story

As dev/ops/QE I'd like to enable a disabled data source without direct database interaction so that we can test provider status flows and enable disabled providers.

Assumptions

• This is a very simple masu API endpoint that takes a provider UUID and a status (e.g. enable/disable) and alters the status in the database.

Implementation Details

• /api/v1/provider_status/?provider_uuid={provider_uuid}&status={enable/disable}

Acceptance Criteria

• [ ] The API can disable and enable a provider

[Bug Triage]

Let's have a discussion to decide whether this should be in Masu or Koku.
