* Remove `rad sync --force` flag
* Remove `rad clone --private` flag
These flags are no longer necessary. Simplify specifying which seed
to fetch from with `--seed` is enough.
* Add `--force` flag to force a fetch even if the node is not a seed.
* Don't fail if we can't connect to a node during a fetch.
* More accurately exit when we hit our replica count.
