* Fix instrumentation to use log target properly.

* Add some tracing instrumentation macros.

* Use int_tags instead of logs.

* Add span per iteration.

* Remove span::log functionality.

* Fix instrumentation log target for real.

* Add jaeger span to responding side as well.

* Revert "Fix instrumentation log target for real."

This reverts commit e1c2a2e6ff6f257e702f07d8a77c2668af92b0ef.

* Revert "Fix instrumentation to use log target properly."

This reverts commit 7caa0bd1acc6fe9727bb3a91851560d756c40ab8.

* target -> subsystem in instrumentatio macro

target is not correct either, and the correct way of using a top level
target = LOG_TARGET does not work, as the macro expects a string literal
and gets confused by the constant `LOG_TARGET`.

* Use kebab-case for spa names.

* WIP: Whole subsystem test.

* New tests compile.

* Avoid needless runtime queries for no validator nodes.

* Make tx and rx publicly accessible in virtual overseer.

This simplifies mocking in some cases, as tx can be cloned, but rx can
not.

* Whole subsystem test working.

* Update node/network/availability-distribution/src/session_cache.rs

* availability distribution, still very wip.

Work on the requesting side of things.

* Some docs on what I intend to do.

as I will likely replace it with something smarter.

* More work, mostly on cache

and getting things to type check.

* Sketch out logic in `FetchTask` for actual fetching.

- Compile fixes.
- Cleanup.

Missing:

- Check for cancel
- Actual querying of peer ids.

* Finish FetchTask so far.

* Directly use AuthorityDiscoveryId in protocol and cache.

* Resolve `AuthorityDiscoveryId` on sending requests.

* Rework fetch_task

- also make it impossible to check the wrong chunk index.
- Export needed function in validator_discovery.

* From<u32> implementation for `ValidatorIndex`.

* Fixes and more integration work.

* Make session cache proper lru cache.

* Use proper lru cache.

* Requester finished.

* ProtocolState -> Requester

Also make sure to not fetch our own chunk.

* Cleanup + fixes.

Currently the first last timestamp is `0` and that leads to the first
slot being `0` which is reserved for genesis. There is some debug assert
