* Create initial `mempool::Crawler` type
The mempool crawler is responsible for periodically asking peers for
transactions to insert into the local mempool. This initial
implementation will periodically ask for transactions, but won't do
anything with them yet.
Also, the crawler is currently configured to be always enabled, but this
should be fixed to avoid crawling while Zebra is still syncing the
chain.
* Add a timeout to peer responses
Prevent the crawler from getting stuck if there's communication with a
peer that takes too long to respond.
* Run the mempool crawler in Zebra
Spawn a task for the crawler when Zebra starts.
* Test if the crawler is sending requests
Create a mock for the `PeerSet` service to intercept requests and verify
that the transaction requests are sent periodically.
* Use `full` Tokio features when testing
Make it simpler to select the features for test builds.

Make it easy to navigate from the `TODO` comment to the current project
planning.
