This patch changes separates the business logic of fetching from the process of
fetching itself. It does this through a sans-IO approach, where a `Fetcher`
provides the necessary state to help drive a fetch forward, without performing
any of the IO itself.
What the `Fetcher` cares about is:
- What nodes are going to be attempted to be fetched from
- In what order should they be attempted
- When should the fetching process be considered finished
The `Fetcher` is then used in `radicle-cli` to drive forward the `sync::fetch`
function, allowing it to only care about the IO.
When a `Patch` or `Issue` is entirely removed from the Git repository,
then there is no update to be made -- instead it should also be
removed from the cache.
This covers the case where the original author of the COB deletes the
COB.

No tests for `rad patch delete` existed.
Add a test where two peers interact on a patch and one decides to
delete the patch. It ensures that the patch is still visible to the
peer that did not delete the patch.
