dev-requirements: pytest-cov==2.6.1 for '--no-cov'

Bump the version of pytest-cov, so that we pick up the fix for
the '--no-cov' option breaking in pytest 4.0:

    https://github.com/pytest-dev/pytest-cov/pull/230

This was the error you would get prior to this version:

    _pytest.warning_types.RemovedInPytest4Warning: config.warn has been
    deprecated, use warnings.warn instead

Although it says 'deprecated', it did result in
termination with stack trace.

Minor correction, looks like we're not observing this queue

.gitlab-ci.yml: Use newer image for overning aarch tests

During recent reorganizing of `.gitlab-ci.yml` to work with `tox`, seems
like we missed to update the image used by the overnight aarch tests,
meaning that they currently fail due to `tox` being missing from them.

While these tests will be skipped on MRs usually, here is an example of
what the tests look like if they are actually run with this change:
https://gitlab.com/BuildStream/buildstream/-/jobs/145449561.

Fixes #859.

_frontend/cli.py: Also check original args for --config in bash completion

The path of the config file generated by testutils for completion tests
is passed as regular argument, not via COMP_WORDS. Use that config file
in complete_artifact() to ensure the test uses the right artifact
directory.

completions.py: Add a test for our artifact ref autocompletions

Since the artifact subcommand group has been created, we have been able
to tab complete both element names and artifact refs as arguments to
the artifact subcommands (e.g. bst artifact log), this commit adds a
test for this.

.gitlab-ci.yml: Add job to attempt to update dependencies

This will help us check if BuildStream is working with the latest
version of dependencies, as per our constraints. This job is allowed to
fail but its failure should signal that we need to add stricter
constraints in some of our `.in` requirements files.

conftest.py: Don't use deprecated get_marker() function

Starting from `pytest` version 4.1.0, `Node.get_marker()` has been
removed, and hence our tests break when running with newer versions of
`pytest`. It was deprecated since a while back but it has recently been
removed completely. Use `get_closest_marker()` as a replacement that is
suggested in the changelog, and seems to work fine for our use case.

See https://github.com/pytest-dev/pytest/pull/4564 for more context on
the upstream issue.

One way of verifying this change is that this should fix the recently
added `tests-fedora-update-deps` job, that was failing before due to
this issue.

buildstream/_gitsourcebase.py: Reduce git history for git describe.

Found during #833.

`git rev-list --boundary tag..HEAD` unfortunately gives boundaries
that are deeper than should when there is a merge commit between `tag`
and `HEAD`. The common ancestory of the two parents of the merge is
a boundary instead of the parent of the branch that is not traversed.

`--ancestry-path` fixes this issue by restricting `git` traversing
those branches.

buildstream/_gitsourcebase.py: Fix case where HEAD is tagged

`git rev-list --boundary HEAD..HEAD` does not return any boundary.
So in this case we need to manually tag the HEAD as a boundary.

_cas: Rename artifactcache folder and move that to a root module

Other components will start to reply on cas modules, and not the artifact cache
modules so it should be organized to reflect this.

conftest.py: Use different artifact directory for integration tests

To ensure we can run integration tests in parallel, use a tempdir
for the artifact cache of each separate integration test run.

This makes it possible to run multiple full test runs including
integration tests in parallel under detox.

_scheduler: Refactor of queues and resources.

This branch makes the following changes:

  * jobs/job.py: No longer stores any interested resource list

    Jobs are ephemeral again, they only ever exist while they
    are running.

  * queues/queue.py: Revert to only handling lists of elements

    Elements pass through the queues, Queue.harvest_jobs()
    replaces Queue.pop_ready_jobs() and now the Queue stops
    creating jobs as soon as there are not enough resources
    for the job.

    Also removed unused `prepare()` abstract method.

  * queues/buildqueue.py: Adapt the part where we launch a job

    This part needs to be reworked anyway, just touch it up for
    now so that it doesnt break with the surrounding changes.

  * jobs/{cachesize,cleanup}job.py: Expose uniform complete callback

    Allows the scheduler to manage resource deallocation for these
    two job completions as a custom thing, at the same phase
    that the Queues take care of their own resource deallocation.

  * resources.py: No longer has knowledge of the job

    Since jobs are ephemeral, they are not a suitable place
    to store the resource identifiers, these must be provided
    by the callers wherever needed.

    Now the main Resources object is owned by the Scheduler
    but shared with Queues, each take care of managing the
    resources of the jobs they create through the same
    resource API.

  * scheduler.py: Reverted to only creating jobs on demand

    This changes the flow of the scheduler such that whenever
    jobs complete, the queues are interrogated for as many
    jobs which can run at the moment but not more; and this
    completely removes the waiting list.

    For the internal cache management jobs, we handle this
    with a little state instead of having a waiting list
    and only launch when the resources permit it.

By abolishing the scheduler waiting list and creating jobs
on demand, we fix the order of element processing and consequently
fix issue #712.

tests/frontend/order.py: Enable the test for build and fix the fetch tests

With the scheduler changes, fetch jobs get automatically skipped
so the output is changed, using a separate repo for each element
fixes the test such that every fetch job gets a job launched.

_artifactcache/artifactcache.py: Rephrase failure message

It was saying "There is not enough space to build the given element.",
this makes me think the error is associated to a specific element, but
this does not make sense to show up in a cleanup task.

Instead say "There is not enough space to complete the build.", which
should be more clear that even after cleaning up there is not enough
space.

element.py: Cleanup temporary staging directories on termination

Use utils._tempdir() which in turn uses _signals.terminator() for
this purpose.

This also changes utils._tempdir() to use utils._force_rmtree()
so that it is safe to use for cleaning up the staging directory.

This patch fixes orphaned temporary directories being left behind
in the artifact cache directory at forceful termination time.
