Closes #4248

Impose additional constraint on configuration consistency:
`validation_upgrade_delay` should not be less than or equal to 1.

See the original issue for more details.

Setting zero as weight may be a source of problems.

The problem is, a rogue validator can shove a lot of duplicated votes
and thus fill a block with work that may well exceed the weight limit.

As was suggested by Alexander Popiak [here][comment], this commit
checks the consistency of the configuration.

This commit refactors the consistency checks. Instead of each individual
setter performs its checks locally, we delegate those checks to the
already existing function `check_consistency`. This removes duplication
and simplifies the logic.

A motivating example of this one is the next PR in the stack that will
introduce a check for a field, which validity depends on the validity of
other two fields. Without this refactoring we will have to place a check
not only to the field in question, but also to the other two fields so
that if they are changed they do not violate consistency criteria. It's
easy to imagine how this can go unwieldy with the number of checks.

This also adds a test that verifies that the default chain spec host
configuration is consistent.

Make check-dependent-* jobs only be executed in PRs instead of both PRs and
master.

Reason 1: The companion is not merged at the same time as the parent PR
([1](https://github.com/paritytech/parity-processbot/issues/347#issuecomment-994729950)),
therefore the pipeline will fail on master since the companion PR is not yet
merged in the other repository. This scenario is demonstrated by the pipeline
of
https://github.com/paritytech/substrate/commit/82cc3746450ae9722a249f4ddf83b8de59ba6e0d.

Reason 2: The job can still fail on master due to a new commit on the companion
PR's repository which was merged after `bot merge` happened, as demonstrated by
the following scheme:

1. Parent PR is merged
2. Companion PR is updated and set to merge in the future
3. In the meantime a new commit is merged into the companion PR repository's
  master branch
4. The `check-dependent-*` job runs on master but, due to the new commit, it
  fails for unrelated reasons

While "Reason 2" can be used as an argument against this PR, in that it would
be useful to know if the integration is failing on master, "Reason 1" should be
taken care of due to this inherent flaw of the current companion build system
design.

The function `has_api` checks that the api + version matches, which
isn't true anymore after bumping the version. The fix is to just compare
the runtime api version being at least `1`.

The runtime version check `runtime_version <= version` was wrong, it
needs to be `>=`. Besides that the `WIDELY_DEPLOYED_API_VERSION` is
removed. The runtime version is already cached, aka we don't always call
into the runtime when requesting the runtime version. So, there is no
need to "optimize" this.

* First step in implementing https://github.com/paritytech/polkadot/issues/4386

This PR:

- Reduces MAX_UNSHARED_UPLOAD_TIME to 150ms
- Increases timeout on collation fetching to 1200ms
- Reduces limit on needed backing votes in the runtime

This PR does not yet reduce the number of needed backing votes on the
node as this can only be meaningfully enacted once the changed limit in
the runtime is live.

* Fix tests.

* Guide updates.

* Review remarks.

* Bump minimum required backing votes to 2 in runtime.

* Make sure node side code won't make runtime vomit.

* cargo +nightly fmt

Refactor the configuration module's initializer_on_new_session in such a
way that it returns the configuration. This would make it inline with
other special initialization routines like `shared`'s or `paras`.

This will be useful in a following PR that will check consistency of the
configuration before setting it.

* alter currently-checking-set to launch work only on new candidates

* fmt

* fix compilation

* address review

* Introduce approvals cache test that ensures approval work is only triggered once for each Candidate Hash

* Fix formatting

* Address Feedback

* Move final message await into handle function

* parachains: Fix configuration module

Closes #4529
Closes #4533

I figured that trying to avoid updates does not really worth it to keep.
This is because we seem to not update the configuration often and when
we do we approach this carefully. Thus possibility of a redundant update
is really negligable. At the same time, if such a redundant update does
happen then the effects of that are really small: just some wasted
storage interactions.

On the other hand, making it work was a little bit annoying. With the
proper fix for the pending updates this would be even more annoying
since now we would have to add combinatorically more cases to test this.

So I figured that I will just scrap that and simplify the code.
