* Do not spam when we can not send a message to a job

There are legal reasons why a job ended. If a job failed, the error is
logged. So, we don't need to log an error when we can not send a message
to a job.

* Review feedback

* Rework `ConnectionsRequests`

Instead of implementing the `Stream` trait, this struct now provides a
function `next()`. This enables us to encode into the type system that
it will always return a value or block indefinitely.

* Review feedback

* Bump version from v0.8.26 to v0.8.27

* bump substrate

* Add an upper number of maximum parallel runtime api requests

Instead of spawning all runtime api requests in the background and using

* 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.

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

This reverts commit 58e46aad038e6517d6d56390c8be65b046a21884.

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

This reverts commit 0d6f38413c7c66b5e9e81dabc587906fa9f82656.

* Revert "REVERT ME: more tracing logging"

This reverts commit 675fd2628e84d1596965280e7314155ef21b28e6.

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

This reverts commit e09e156493430b33b6c8ab4b5cedb3f2f91afd51.

* 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 8ce5f4f0bd7186dade134b118751480f72ea1fd6.

* try_runtime_api more to reduce silent exits

* add sanity check that returned backed candidates preserve ordering

* remove redundant err attribute

* include new parameter in test `Configuration`

* update calls to `init_logger`

* "Update Substrate"

* cargo update -p sp-io

* parachains runtime: configurable maximum validators per core

* update guide and add test

* refactor some functions to not rely on `self`

* factor out common elements of seconding and attesting

* Add Spawn to backing FromJob

* do candidate validation in background

* tests

* address grumbles

* Simplify subsystem jobs

This pr simplifies the subsystem jobs interface. Instead of requiring an
extra message that is used to signal that a job should be ended, a job
now ends when the receiver returns `None`. Besides that it changes the
interface to enforce that messages to a job provide a relay parent.

* Drop ToJobTrait

* Remove FromJob

We always convert this message to FromJobCommand anyway.

* rename Trait -> Config

* revert diener changes

* rename HostConfig to ActiveConfig as more meaningful

This pr changes how the runtime api subsystem processes runtime api
requests. Instead of answering all of them in the subsystem task and
thus, making all requests sequential, we now answer them in a background
task. This enables us to serve multiple requests at once.
