Update data manager URL for local environment in SDK

[luzzif]

In the SDK we are currently using the dev environment data manager service URL in the local environment, which means that all campaigns created locally to test out Carrot are stored in the shared S3 bucket where we also store dev and staging data.

carrot-scripts must be updated so that a local instance of S3 (MinIO) gets bootstrapped replacing the current IPFS node service, and then the SDK data manager URL can be replaced with the MinIO S3 API endpoint.
