Manage node failure: Await all nodes to finish before marking dataflow as finished

Use `DoraStatus` from dora library in template

This commit enables users to pass environment variable as composition
of env variable such as:

```yaml
  - id: yolov5
    operator:
      outputs:
        - bbox
        - ready
      inputs:
        image: oasis_agent/image
        check: oasis_agent/yolov5_check
      python: ../../operators/yolov5_op.py
    env:
      YOLOV5_PATH: $HOME/Documents/dependencies/yolov5
      YOLOV5_WEIGHT_PATH: $DORA_DEP_HOME/dependencies/yolov5/yolov5n.pt
```

Note that this is only for the env field. Expanding env variable for
source path might conflict with using url as source path.

Previouly, if one node failed we would immidiately mark the dataflow as
finished even though other nodes might still be running.

This meant that if one node failed, it would not be possible to stop the
dataflow through the cli as it is marked as finished.

This commit will just warn the user that one node failed but will keep
await that all nodes within the dataflow finishes.

Create a changelog file

To prepare for future feature, this commit initiate a `__init__.py` file
that makes the dora python node api, a mixed python/rust project.

Any python function or variable included in the `__init__.py` will be
distributed along rust function declared in `src/lib.rs`.

https://github.com/dora-rs/dora/issues/163 has shown the limitation on
depending too much on `pyo3`.

To alievate the unbounded memory growth, we're replacing variable dereferencing
with scoped `GILPool` as described in the pyo3 documentation recently updated. See:
https://github.com/PyO3/pyo3/pull/2864

This commit fix the memory leak happening in the dora API operator. This
is seemingly due to pyo3 leaking memory on object created in Rust.
Using standard `drop` did not drop the memory on the `PyBytes` included in
the `PyDict`.

See: https://github.com/PyO3/pyo3/issues/1801

Fixes https://github.com/dora-rs/dora/issues/163

This commit improve the CI/CD by testing the newly added CLI commands:
- `up`
- `list`
- `check`
- `destroy`
- `start`
- `stop`

This commit also removes not needed anymore capnp dependencies to simplify
the CI.

Use python as source for `python` example

add binaries to `$GITHUB_PATH`

Add up command in test

Remove not necessary change

Add CLI start and stop test

Add removed iceoryx test

This way, we don't need to update the version manually in all sub-crates on every release.

Fix high CPU usage in coordinator by properly handling closed connections

We forgot to handle closed control connections in the `handle_requests` loop. So instead of breaking out of that loop, we continued polling the connection for new messages again and again.

Release v0.1.1
