T1. Fix isolated connection bugs, improve tests, upgrade dependencies (#3302)
* Make handshakes generic over AsyncRead + AsyncWrite * Simplify connect_isolated using ServiceExt::map_err and BoxError * Move isolated network tests to their own module * Improve isolated TCP connection tests * Add an in-memory connection test that uses AsyncReadWrite * Support connect_isolated on testnet * Add a wrapper function for isolated TCP connections to an IP address * Run test tasks for a while, and clean up after them * Upgrade Zebra dependencies to be compatible with arti, but don't add arti yet * Fix deny.toml Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> Co-authored-by: Conrado Gouvea <conrado@zfnd.org>
