Submit repo to databrickslabs for Marketplace eligibility

[rautsamir]

Marketplace requires the app to be checked into github.com/databrickslabs. This requires going through the Labs Submission Process — code review and approval from the Labs team. Can be a sandbox project or top-level project.

Current repo: github.com/databricks-field-eng/datamarket (and mirror at rautsamir/datamarket-databricks)

Action: Start Labs submission process. See: https://github.com/databrickslabs

PR submitted: databrickslabs/sandbox#919

Sandbox path chosen (faster, can promote to top-level later). Reviewers auto-assigned. Awaiting maintainer approval from @nfx / @alexott.
