chore(helm,docker): add artifact-backend-init cmd (#1175)

Because

- We are refactoring the preset pipeline mechanism. The preset pipelines
will now be created programmatically by other services instead of being
downloaded via the preset pipeline downloader. For example, the preset
pipelines used by artifact-backend will be created by artifact-backend
itself.

This commit

- adds artifact-backend-init cmd for creating preset pipelines.
