Add e2e test on neuro run --volume=ALL with shared resources

[atemate]

Once "Automount: neuro run --volume=ALL" is merged, we need to add a e2e test which checks that all storage resources shared with the user (including files) were mounted to /var/storage.

How to use two helpers set up to 2 different users:

Draft for the test:

@pytest.mark.e2e
def test_job_run_volume_all(helper: Helper, another_helper: Helper, data: Tuple[str, str], request: Any) -> None:
    helper_1 = helper
    helper_2 = another_helper

    path_1 = f"{uuid4()}/"  # read
    path_2 = f"{path_1}/{uuid4()}.txt"  # write
    path_3 = f"path/to/{uuid4()}/"  # manage

    request.addfinalizer(lambda: remove_storage_obj(helper_1, path_1, recursive=True))
    request.addfinalizer(lambda: remove_storage_obj(helper_1, path_3))

    local_temp_file, checksum = data
    helper_1.run_cli(["storage", "mkdir", f"storage:{path_1}"])
    helper_1.run_cli(["storage", "cp", local_temp_file, f"storage:{path_1}"])
    helper_1.run_cli(["storage", "mkdir", "-p", f"storage:{path_3}"])

    shared = [
        (f"storage://{helper_1.username}/{path_1}", "read"),
        (f"storage://{helper_1.username}/{path_2}", "write"),
        (f"storage://{helper_1.username}/{path_3}", "manage"),
    ]
    for uri, action in shared:
        request.addfinalizer(lambda: revoke(helper_1, uri, helper_2.username))
        helper_1.run_cli(["acl", "grant", uri, helper_2.username, action])

    received = helper_2.run_cli(["acl", "list"])
    assert all(f"{uri} {action}" in received for uri, action in shared)

    cmd = " && ".join([
        f"[ -d /var/storage/{path_1} ]",
        f"[ -d /var/storage/{path_2} ]",
        f"[ -d /var/storage/{path_3} ]",
        "[ -d /var/storage/home ]",
        "[ $NP_STORAGE_ROOT_MOUNTPOINT == /var/storage ]",
    ])
    command = f"bash -c '{cmd}'"

    # first, run without --volume=HOME
    helper_2.run_job_and_wait_state(
        image=UBUNTU_IMAGE_NAME, command=command, wait_state=JobStatus.FAILED
    )

    # then, run with --volume=HOME
    helper_2.run_job_and_wait_state(
        image=UBUNTU_IMAGE_NAME,
        command=command,
        params=("--volume", "ALL"),
        wait_state=JobStatus.SUCCEEDED,
    )


def remove_storage_obj(helper: Helper, path_uri: str, recursive: bool = False) -> None:
    try:
        args = recursive and ["--recursive"] or []
        helper.run_cli(["storage", "rm", path_uri] + args)
    except subprocess.CalledProcessError:  # let's ignore any possible errors
        pass
