Client-side dependencies now also needed on server side

[tieneupin]

Encountered these issues while trying to run murfey.server --demo after installing only murfey[server].

• The client-side .murfey file is needed
• Textual is needed

$ murfey.server --demo

Murfey client configuration file /root/.murfey not found

There is a possibility that the initialisation of murfey.util.__init__ is what leads to the "Murfey client configuration file /root/.murfey not found" warning.

This warning can be found in the read_config() function:

python-murfey/src/murfey/util/__init__.py

Lines 27 to 40 in 19f2f31

	def read_config() -> configparser.ConfigParser:
	config = configparser.ConfigParser()
	try:
	mcch = os.environ.get("MURFEY_CLIENT_CONFIG_HOME")
	murfey_client_config_home = Path(mcch) if mcch else Path.home()
	with open(murfey_client_config_home / ".murfey") as configfile:
	config.read_file(configfile)
	except FileNotFoundError:
	logger.warning(
	f"Murfey client configuration file {murfey_client_config_home / '.murfey'} not found"
	)
	if "Murfey" not in config:
	config["Murfey"] = {}
	return config

It is used later on in authorised_requests(), which is then used to set requests.get, requests.post, requests.put, requests.delete:

python-murfey/src/murfey/util/__init__.py

Lines 53 to 62 in 19f2f31

	def authorised_requests() -> Tuple[Callable, Callable, Callable, Callable]:
	token = read_config()["Murfey"].get("token", "")
	_get = partial(requests.get, headers={"Authorization": f"Bearer {token}"})
	_post = partial(requests.post, headers={"Authorization": f"Bearer {token}"})
	_put = partial(requests.put, headers={"Authorization": f"Bearer {token}"})
	_delete = partial(requests.delete, headers={"Authorization": f"Bearer {token}"})
	return _get, _post, _put, _delete
	requests.get, requests.post, requests.put, requests.delete = authorised_requests()

If we really want to separate the client and server branches, would migrating this to a separate util file under murfey.client work?

Partially addressed by PR #448.
On the server side, a warning still appears on startup saying that that the client configuration was not found, but it doesn't error any more.
