Description

Starting a server w/authentication, then connecting to it via a python thin client w/an incorrect username and password.

The message/stacktrace is ambiguous leading clients to believe that they've connected, and something is amiss w/the server.

client = Client(username='incorrect-user-name', password='incorrect-password', use_ssl=False)
client.connect('127.0.0.1', 10800)


#client(nodes)
print("connected to: ".format(client))
print("cache names: ".format(client.get_cache_names))

the stacktrace is :

connected to: 
Traceback (most recent call last):
cache names: 
  File "C:/dev/python-thin-client/examples/get_and_put.py", line 30, in <module>
    print(client.get_cache_names())
  File "C:\dev\python-thin-client\pyignite\utils.py", line 249, in ste_wrapper
    result = fn(*args, **kwargs)
  File "C:\dev\python-thin-client\pyignite\client.py", line 521, in get_cache_names
    return cache_get_names(self.random_node)
  File "C:\dev\python-thin-client\pyignite\utils.py", line 273, in wrapper
    return func(obj, *args, **kwargs)
  File "C:\dev\python-thin-client\pyignite\client.py", line 222, in random_node
    raise ReconnectError('Can not reconnect: out of nodes.') from None
pyignite.exceptions.ReconnectError: Can not reconnect: out of nodes.

ReconnectError: Can not reconnect: out of nodes exception: allows the user to make the conclusion that the connection is successful, but something is wrong with the server.
