migrate OSO impact metrics to v1

[ccerv1]

Overview OSO is releasing a stable v1 of its API. For your queries, functionality will be identical to what you had previously, but the schema is a little different.

You can view the new models here.

Details

In order to replicate the same queries you implemented here, the relevant models are:

artifacts_by_project_v1: {
    project_id
  }

and

code_metrics_by_project_v1 {
    contributor_count
    first_commit_date
  }

We are also pushing a stable events_monthly_to_project_v1 model 🔜 (hopefully by the time you read this).
