feat: send client version to server

[natthan-pigoux]

• create a middleware to check that the client version pass in header is recent enough from what is defined in the entry_point

[natthan-pigoux]

closes #258

• Need to check why the send or send_request client method are not used to send the request.
• It looks like the request goes through: client/aio/operations/_operations.py > self._client._pipeline.run when testing with userinfo

@chaen find how to add properly the header in the client:
kwargs.setdefault("base_headers", {})[DiracX-Client-Version"] = self.client_version

Do I need to add more unit tests ?

Do I need to add more unit tests ?

• a test when the header is missing? (which might be the case if we interact with the server using the openapi or the web interface)
• a test when the header is present but does not contain any value?
• a test when something other than a version is provided? Making sure the server correctly handles weird strings or numbers and does not crash.
