The pymongo dependency for edx-platform was updated (3.10.1 to 3.12.3)
in https://github.com/openedx/edx-platform/pull/30569
This caused the following error when running the edx-platform database
migration split_modulestore_django.0002_data_migration as part of
`tutor dev quickstart`:
pymongo.errors.ServerSelectionTimeoutError: client is configured to

This commit explicitly sets replicaSet to None to indicate that it's a
standalone MongoDB instance. I also had to remove the CONTENTSTORE entry
from auth.yml because edx-platform's devstack.py assumes it has a
non-null value (set in common.py), and devstack.py executes before
tutor's development.py can set this replicaSet value.

The -m/--mount option makes it possible to bind-mount volumes at runtime. The
volumes are declared in a local/docker-compose.tmp.yml file. The problem with
this approach is when we want to bind-mount a volume to a service which is
specific to the dev context. For instance: the "learning" service when the MFE
plugin is enabled.
In such a case, starting the service triggers a call to `docker-compose stop`
in the local context. This call fails because the "learning" service does not
exist in the local context. Note that this issue only seems to occur with
docker-compose v1.
To resolve this issue, we create two additional filters for
the dev context, which emulate the behaviour of the local context. With this approach, we convert the -m/--mount arguments right after they are parsed. Because they are parsed just once, we can get rid of the de-duplication logic initially introduced with the COMPOSE_CLI_MOUNTS context.
Close #711. Close also https://github.com/overhangio/tutor-mfe/issues/57.
Whenever Tutor executes a shell command, it logs out said
command in order to aid in end user understanding/debugging.
In some cases (notably, when running jobs in containers)
the logged command was not accurately quoted. The command
was run correctly, because it was passed in pieces to
``subprocess.Popen``, which correctly joins the pieces together
into a valid POSIX shell command; however, the logged version
of the command was constructed by simply joining the pieces
with spaces. This usually works, but breaks down when running
complex shell commands with nested quoting.
This commit changes the logging to use ``shlex.join``, which
joins command pieces together in a POSIX-compliant way,
presumably the same way as ``subprocess.Popen``.
Example:
tutor local importdemocourse
runs the shell command:
docker-compose -f /home/kyle/.local/share/tutor/env/local/docker-compose.yml -f /home/kyle/.local/share/tutor/env/local/docker-compose.prod.yml -f /home/kyle/.local/share/tutor/env/local/docker-compose.tmp.yml --project-name tutor_local -f /home/kyle/.local/share/tutor/env/local/docker-compose.jobs.yml -f /home/kyle/.local/share/tutor/env/local/docker-compose.jobs.tmp.yml run --rm cms-job sh -e -c 'echo "Loading settings $DJANGO_SE... (several more script lines) ...eindex_course --all --setup'
but the logged shell command was:
docker-compose -f /home/kyle/.local/share/tutor/env/local/docker-compose.yml -f /home/kyle/.local/share/tutor/env/local/docker-compose.prod.yml -f /home/kyle/.local/share/tutor/env/local/docker-compose.tmp.yml --project-name tutor_local -f /home/kyle/.local/share/tutor/env/local/docker-compose.jobs.yml -f /home/kyle/.local/share/tutor/env/local/docker-compose.jobs.tmp.yml run --rm cms-job sh -e -c echo "Loading settings $DJANGO_SE... (several more script lines) ...eindex_course --all --setup
which will not run if copied and pasted back into the
user's terminal, as the importdemocourse shell script is unquoted.
When waiting for pods, it's possible that the deployment may be
complete but, because other pods may have been Evicted or Killed, the
wait wait condition completes.
In certain code paths, such as in `tutor local quickstart`,
`process_mount_points` is called more than once in the same process,
causing mounts to be added to `COMPOSE_LOCAL[_JOBS]_TMP` redundantly.
As a result, docker-compose[.jobs].tmp.yml was occasionally being
rendered with duplicate volume specifiers. Some versions of Docker
Compose ignored this; other versions warned or threw an error.
In order to make `process_mount_points` tolerant to being called
multiple times, we wrap its volume-adding callbacks within a new
hooks context. This allows us to clear said hooks context every
time `process_mount_points` is called, essentially making the
function idempotent.

Sometimes, the host user is root: this may happen when tutor is run with
"sudo" (which is not recommended) or on Windows. In such cases, building
the image should not fail, but default to a reasonable user. Also, when
we pass an invalid APP_USER_ID as a build arg, then we should fail with
an explicit message.

Currently there is no way for plugins to customize Kubernetes resources
defined in Tutor deployment manifests.
This change makes that possible by taking advantage of the strategic
merge patching mechanism in `kustomization.yml`.
Any resource definition in a `k8s-override` patch in a plugin will
override the resource defined by Tutor, provided that their names match.

- [Improvement] Use `git am` instead of `cherry-pick` to simplify patching process.
- [Improvement] Tutor is now compatible with Docker Compose subcommand.
PYTHONBREAKPOINT has been exposed as an environment variable in
the openedx Dockerfile available to be changed in config.yml. The docs have also been changed to recommend using
breakpoint and explaining how PYTHONBREAKPOINT can be modified to use a
custom debugger.
