Decouple the cli from the config schema

[Benjamin-Nussbaum]

At the moment, if we change one thing in the config, there are multiple things that have to change to keep the cli up to date. E.g.,

pqn-stack/src/pqnstack/cli.py

Lines 23 to 35 in 2d0fe14

	for i, item in enumerate(instruments):
	if "name" not in item:
	msg = f"Instrument number #{i + 1} configuration is missing the field 'name'"
	raise InvalidNetworkConfigurationError(msg)
	if "import" not in item:
	msg = f"Instrument number #{i + 1} configuration is missing the field 'import'"
	raise InvalidNetworkConfigurationError(msg)
	if "desc" not in item:
	msg = f"Instrument number #{i + 1} configuration is missing the field 'desc'"
	raise InvalidNetworkConfigurationError(msg)
	if "address" not in item:
	msg = f"Instrument number #{i + 1} configuration is missing the field 'address'"
	raise InvalidNetworkConfigurationError(msg)

pqn-stack/src/pqnstack/cli.py

Lines 55 to 64 in 2d0fe14

	if "name" in provider:
	kwargs["name"] = str(provider["name"])
	if "router_name" in provider:
	kwargs["router_name"] = str(provider["router_name"])
	if "host" in provider:
	kwargs["host"] = str(provider["host"])
	if "port" in provider:
	kwargs["port"] = int(provider["port"])
	if "beat_period" in provider:
	kwargs["beat_period"] = int(provider["beat_period"])

pqn-stack/src/pqnstack/cli.py

Lines 109 to 118 in 2d0fe14

	if name:
	kwargs["name"] = name
	if router_name:
	kwargs["router_name"] = router_name
	if host:
	kwargs["host"] = host
	if port:
	kwargs["port"] = port
	if beat_period:
	kwargs["beat_period"] = beat_period

Ideally the cli should be aware of the config schema and other models.
