* guide: non-semantic changes
* guide: update per the issue description
* GetBackedCandidates operates on multiple hashes now
* GetBackedCandidates still needs a relay parent
* implement changes specified in guide
* distinguish between various occasions for canceled oneshots
* add tracing info to getbackedcandidates
* REVERT ME: add tracing messages for GetBackedCandidates
Note that these messages are only sometimes actually passed on to the
candidate backing subsystem, with the consequence that it is
unexpectedly frequent that the provisioner fails to create its
provisionable data.
* REVERT ME: more tracing logging
* REVERT ME: log when CandidateBackingJob receives any message at all
* REVERT ME: log when send_msg sends a message to a job
* fix candidate-backing tests
* streamline GetBackedCandidates
This uses table.attested_candidate instead of table.get_candidate, because
it's not obvious how to get a BackedCandidate from just a
CommittedCandidateReceipt.
* REVERT ME: more logging tracing job lifespans
* promote warning about job premature demise
* don't terminate CandiateBackingJob::run_loop in event of failure to process message
* Revert "REVERT ME: more logging tracing job lifespans"
This reverts commit 7365f2fb3dec988d95cfcd317eba75587fe7fd16.

* use unique error variants for each canceled oneshot
* Revert "REVERT ME: add tracing to candidate-backing job creation"
This reverts commit 8ce5f4f0bd7186dade134b118751480f72ea1fd6.
* try_runtime_api more to reduce silent exits
* add sanity check that returned backed candidates preserve ordering
* remove redundant err attribute
We need to distribute the PoV after we have seconded it. Other nodes
that will receive our `Secondded` statement and want to validate the
candidate another time will request this PoV from us.
* Do not validate a candidate in candidate selection
The candidate selection subsystem should not validate a candidate, as
this is done by the backing subsystem on a `Second` request. Otherwise
we validate one candidate twice.
* Update candidate-selection.md
* choose the straightforward candidate selection algorithm for now
* add draft implementation of candidate selection
* fix typo in summary
* more properly report misbehaving collators
* describe how CandidateSelection subsystem becomes aware of candidates
* revise candidate selection / collator protocol interaction pattern
* implement rest of candidate selection per the guide
* review: resolve nits
* start writing test suite, harness
* implement first test
* add second test
* implement third test
