[rust core] multi key command with no arguments, in cluster mode, panics

[eifrah-aws]

Consider the following example (in python, but crashes in every binding):

# Use full path
addresses = [NodeAddress("127.0.0.1", 7000), NodeAddress("127.0.0.1", 8000)]
config = GlideClusterClientConfiguration(addresses)
client = await GlideClusterClient.create(config)

for i in range(10000):
    response = await client.mset({})
    if "ERR" in response:
        print(f"error: {response}")

Same code using standalone client, (GlideClient) reports a proper error message:

lide.exceptions.RequestError: An error was signalled by the server - ResponseError: wrong number of arguments for 'mset' command
