feat: support --dry-run operations
What
feat: support --dry-run operations
When running with --dry-run no commit nor pipeline will be generated.
Commit and pipeline data will be shown on stdout instead.
A (read-only) token may be necessary for some operations requiring access to the ring definitions.
Why
Sometimes we just want to see the output of a data transformation without commit it, this replaces the old --local mode.
