Refactor to create a new `zebra-node-services` crate (#3648)
* Create new empty `zebra-node-services` crate

The goal is to store the mempool `Request` and `Response` types so that
the `zebra-rpc` crate can interface with the mempool service without
having to import `zebrad`.

* Move `Gossip` mempool type into new crate

It is required by the `Request` type, which will be moved next.

* Add documentation to `Gossip` variants

Avoid having to add an exception to allow undocumented code.

* Move `mempool::Request` type to new crate

The first part of the service interface definition. Usages have been
changed to refer to the new crate directly, and since this refactor is
still incomplete, some `mp` aliases are used in a few places to refer to
the old module.

* Create an `UnboxMempoolError` helper trait

Centralize some common code to extract and downcast boxed mempool
errors. The `mempool::Response` will need to contain a `BoxError`
instead of a `MempoolError` when it is moved to the
`zebra-node-services` crate, so this prepares the tests to be updated
with less changes.

* Use `UnboxMempoolError` in tests

Make the necessary changes so that the tests are ready to support a
`BoxError` in the `mempool::Response` type.

* Use `BoxError` in `mempool::Response`

Prepare it to be moved to the `zebra-node-services` crate.

* Move `mempool::Response` to `zebra-node-services`

Update usages to import from the new crate directly.

* Remove `mp` aliases for mempool component module

Use any internal types directly instead.

* Replace `tower::BoxService` with custom alias

Remove the dependency of `zebra-node-services` on `tower`.

* Move `Gossip` into a separate `sub-module`

Keep only the main `Request` and `Response` types in the `mempool`
module.

* Use `crate::BoxError` instead of `tower::BoxError`

Follow the existing convention.

* Add missing `gossip.rs` module file

It was missing from a previous refactor commit.

4. Avoid repeated requests to peers after partial responses or errors (#3505)
* fix(network): split synthetic NotFoundRegistry from message NotFoundResponse

* docs(network): Improve `notfound` message documentation

* refactor(network): Rename MustUseOneshotSender to MustUseClientResponseSender

```
fastmod MustUseOneshotSender MustUseClientResponseSender zebra*
```

* docs(network): fix a comment typo

* refactor(network): remove generics from MustUseClientResponseSender

* refactor(network): add an inventory collector to Client, but don't use it yet

* feat(network): register missing peer responses as missing inventory

We register this missing inventory based on peer responses,
or connection errors or timeouts.

Inbound message inventory tracking requires peers to send `notfound` messages.
But `zcashd` skips `notfound` for blocks, so we can't rely on peer messages.
This missing inventory tracking works regardless of peer `notfound` messages.

* refactor(network): rename ResponseStatus to InventoryResponse

```sh
fastmod ResponseStatus InventoryResponse zebra*
```

* refactor(network): rename InventoryStatus::inner() to to_inner()

* fix(network): remove a redundant runtime.enter() in a test

* doc(network): the exact time used to filter outbound peers doesn't matter

* fix(network): handle block requests slightly more efficiently

* doc(network): fix a typo

* fmt(network): `cargo fmt` after rename ResponseStatus to InventoryResponse

* doc(test): clarify some test comments

* test(network): test synthetic notfound from connection errors and peer inventory routing

* test(network): improve inbound test diagnostics

* feat(network): add a proptest-impl feature to zebra-network

* feat(network): add a test-only connect_isolated_with_inbound function

* test(network): allow a response on the isolated peer test connection

* test(network): fix failures in test synthetic notfound

* test(network): Simplify SharedPeerError test assertions

* test(network): test synthetic notfound from partially successful requests

* test(network): MissingInventoryCollector ignores local NotFoundRegistry errors

* fix(network): decrease the inventory rotation interval

This stops us waiting 3-4 sync resets (4 minutes) before we retry a missing block.

Now we wait 1-2 sync resets (2 minutes), which is still a reasonable rate limit.
This should speed up syncing near the tip, and on testnet.

* fmt(network): cargo fmt --all

* cleanup(network): remove unnecessary allow(dead_code)

* cleanup(network): stop importing the whole sync module into tests

* doc(network): clarify syncer inventory retry constraint

* doc(network): add a TODO for a fix to ensure API behaviour remains consistent

* doc(network): fix a function doc typo

* doc(network): clarify how we handle peers that don't send `notfound`

* docs(network): clarify a test comment

3. Send notfound when Zebra doesn't have a block or transaction (#3466)
* refactor(network): rename Advertised to Available

```sh
fastmod Advertised Available zebra*
fastmod advertised available zebra*
```

* refactor(network): allow different available and missing types inside an InventoryStatus

And rename it to ResponseStatus.

Split the methods between ResponseStatus and an InventoryStatus alias.

* refactor(network): add a block_hash convenience method to InventoryHash

* test(network): improve failure logs for connection tests

* fix(inbound): move address sanitization into the response future

* feat(network): send notfound when Zebra doesn't have a block or transaction

* doc(network): move module docs to the top of each module

This makes them more likely to get updated when the module changes.

* fix(network): stop sending unsupported missing inventory types to the registry

* test(network): inbound messages are forwarded to the registry

* test(inbound): test Peers requests to the inbound service, directly and via TCP

* test(network): notfound block responses are sent by the inbound service

* test(network): notfound tx responses are sent by the inbound service

* test(network): increase sync test mock service timeout

The code that these tests use hasn't actually changed much,
and they are only failing on some platforms (coverage, macOS).

So it seems like the extra concurrent inbound tests have pushed them
past their time limit.
(Perhaps due to TCP system calls, or extra serialization work.)

* doc(network): fix typo

* test(network): remove unnecessary multi-threaded runtime from tests

This prevents `MockService<zebra_state>` timeouts
in the `sync_block_too_high_extend_tips` test,
at the cost of reducing coverage of different execution orders.
