We don't want to link to pythonlib when compiling the dora-daemon.

Previous implementation of the runtime would link `libpython` even though it
might not be required.

This commit put pyo3 dependency under a feature flag that is only active if
the runtime is called from python for a python operator.

The `tracing` feature just enables the tracing subscriber, the `telemetry` feature the `opentelemetry` integration.

Removing those path make it easier to move package, reduce path management
reduce complexity and make it easier to export crates to `crates.io`

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

This commit is an initial draft at fixing #147. The error is due to the
fact that pyo3 has linked the libpython from the compilation and not
trying to use libpython that is available in `LD_LIBRARY_PATH`.

The current only solution to disable the linking is to use the `extension-module` flag.
This requires to make the python `runtime-node` packaged in a python library.
The python `runtime-node` should also be fully compatible with the other operators in case we want hybrid runtime.

The issue that i'm facing is that. Due to the packaging, I have to deal with the `GIL` that is present from the start of
`dora-runtime` node. This however makes the process single threaded wich is impossible.

So, I have to disable it, but when I do, I have a race condition:
```bash
Exception ignored in: <module 'threading' from '/usr/lib/python3.8/threading.py'>
Traceback (most recent call last):
  File "/usr/lib/python3.8/threading.py", line 1373, in _shutdown
    assert tlock.locked()
AssertionError:
```
The issue is the same as https://github.com/PyO3/pyo3/issues/1274

To fix this issue, I'm going to look again at the different step to make this work.

But this is my current investigation.

Pinning zenoh git version to fix recompilation of the `dora-api-operator` when it
is a user dependency.

Parsing as URI does not work for relative paths, e.g. `../../foo`.

Makes it possible to set an URL as operator source. The `dora-runtime` will then try to download the operator from the given URL when the dataflow is started.

* Add a `dora-python-operator` crate to hold utils functions for dora python

* Remove python serialisation and deserialisation from `dora-runtime`

* Update `python` documentation

* add opentelemetry feature to python op

* modify `python-dataflow` to test opentelemetry

* change `timer` topic to `tick`

* adding tracing to `shared_libraries`

* example install refactoring

* Rename `input` to `dora_input` for python ex
