Minor Updates to Seeded Crawl control descriptions & names

- Renames the first step as `Crawl Scope` from `Crawl Setup`.  Technically this whole process is setting up crawls, `Crawl Scope` should be more descriptive.
- Changes the help text regarding crawler instances to mention rate limiting instead of the amount of resources it takes up on our end which isn't terribly relevant to users.
