* 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 7365f2fb.

* Revert "REVERT ME: log when send_msg sends a message to a job"

This reverts commit 58e46aad.

* Revert "REVERT ME: log when CandidateBackingJob receives any message at all"

This reverts commit 0d6f3841.

* Revert "REVERT ME: more tracing logging"

This reverts commit 675fd262.

* Revert "REVERT ME: add tracing messages for GetBackedCandidates"

This reverts commit e09e1564.

* formatting

* add logging message to CandidateBackingJob::run_loop start

* REVERT ME: add tracing to candidate-backing job creation

* run candidatebacking loop even if no assignment

* use unique error variants for each canceled oneshot

* Revert "REVERT ME: add tracing to candidate-backing job creation"

This reverts commit 8ce5f4f0.

* try_runtime_api more to reduce silent exits

* add sanity check that returned backed candidates preserve ordering

* remove redundant err attribute

See https://github.com/rust-lang/rust/issues/54540

* include new parameter in test `Configuration`

* update calls to `init_logger`

* "Update Substrate"

* cargo update -p sp-io

This change is to make it more similar to what we have in cumlus.

This is not a big change since the user definition AbstractClient already is 'static.
