Runs the pending migrations for the given repository.

The repository must be set under :ecto_repos in the current app configuration or given via the -r option.

By default, migrations are expected at “priv/YOUR_REPO/migrations” directory of the current application but it can be configured to be any subdirectory of priv by specifying the :priv key under the repository configuration.

Runs all pending migrations by default. To migrate up to a version number, supply --to version_number. To migrate up a specific number of times, use --step n.

If the repository has not been started yet, one will be started outside our application supervision tree and shutdown afterwards.
