but keep zenoh log level at WARN level

The previous machine ID is still used, but optional. Users don't need to ensure that the chosen machine IDs are unique anymore because they are augmented with a UUID.

Bump dora to 0.3.7-rc1

Minor dependency fix

Fix typo

Runs a dataflow locally, without requiring any any daemon or coordinator
processes. Multi-machine dataflows are not supported. The default log
level is set to `INFO`, overwriting it is possible by setting the
`RUST_LOG` environment variable.

This exposes the internal `dora daemon --run-dataflow` command that we
use for testing.

The second commit adds a ctrl-c handler. On first ctrl-c, we send a stop
command to all nodes. On second ctrl-c, we exit immediately and kill all
spawned nodes. On third ctrl-c, we abort the process directly without
waiting (child processes keep running).

Make `dora-message` a dependency of `dora-core`, instead of the other way around. This way, we can continue to freely bump the version of `dora-core` with the other workspace crates, without introducing errors such as #708.

It is necessary to make build multiline in order to build certain node. 

This allow users to do the following:

```bash
nodes:
  - id: dora-microphone
    build: |
      pip install -e ../../node-hub/dora-microphones
      pip install -e ../../node-hub/dora-vad
    path: dora-microphone
```

or

```bash
nodes:
  - id: dora-microphone
    build: |
      sudo apt install abc
      pip install bar
    path: dora-microphone
```

This PR fixes one error that happen when the coordinator fail to connect
to the daemon and ultimately hangs indefinetely.

## To reproduce previous behaviour:

```bash
dora up
kill <DAEMON PID> && dora destroy
dora destroy # <- This hangs
```
