This changes how the scheduler works and adapts all the code that needs
adapting in order to be able to run in threads instead of in
subprocesses, which helps with Windows support, and will allow some
simplifications in the main pipeline.
This addresses the following issues:
* Fix #810: All CAS calls are now made in the master process, and thus
share the same connection to the cas server
* Fix #93: We don't start as many child processes anymore, so the risk
of starving the machine are way less
* Fix #911: We now use `forkserver` for starting processes. We also
don't use subprocesses for jobs so we should be starting less
subprocesses
And the following highlevel changes where made:
* cascache.py: Run the CasCacheUsageMonitor in a thread instead of a
subprocess.
* casdprocessmanager.py: Ensure start and stop of the process are thread
safe.
* job.py: Run the child in a thread instead of a process, adapt how we
stop a thread, since we ca't use signals anymore.
* _multiprocessing.py: Not needed anymore, we are not using `fork()`.
* scheduler.py: Run the scheduler with a threadpool, to run the child
jobs in. Also adapt how our signal handling is done, since we are not
receiving signals from our children anymore, and can't kill them the
same way.
* sandbox: Stop using blocking signals to wait on the process, and use
timeouts all the time.
* messenger.py: Use a thread-local context for the handler, to allow for
multiple parameters in the same process.
* _remote.py: Ensure the start of the connection is thread safe
* _signal.py: Allow blocking entering in the signal's context managers
by setting an event. This is to ensure no thread runs long-running
code while we asked the scheduler to pause. This also ensures all the
signal handlers is thread safe.
* source.py: Change check around saving the source's ref. We are now
running in the same process, and thus the ref will already have been
changed.

Plugin tests are already accessing this API, but using imports from
private modules. For motivation for this to be exposed publicly, note
that ErrorDomain is an argument for most things in runcli.py, and
LoadErrorReason may be another.

As discussed over the mailing list, reformat code using Black. This is a
one-off change to reformat all our codebase. Moving forward, we
shouldn't expect such blanket reformats. Rather, we expect each change
to already comply with the Black formatting style.

Currently, the `BaseRemote` would call `_check()` on the children, which
states that errors should be sent back as a string. However,
`BaseRemote` doesn't check the return of `_check()`.
This changes the contract so that subclasses throw `RemoteError`
themselves.
This also fixes the `ArtifactShare` and add a test.

This ensures we correctly expand "~" in paths to certificates

This is no longer required as gRPC connections are closed before fork.

This is now split into storage/index remotes, where the former is
expected to be a CASRemote and the latter a BuildStream-specific
remote with the extensions required to store BuildStream artifact
protos.

This was almost entirely just historical code duplication.
