Subject: [PATCH] feat(repo): Improve error message for missing
 repositories.yaml

New users to helm don't always run `helm init` (e.g. if their cluster
already has helm installed).  The user's initial interaction with any of
helm's repository commands (e.g. `helm repo list`) will then be an error
message due to a missing repositories.yaml in their local config.

Give the user a little hint about how to fix the error without them having
to hunt through the man/help pages.
