More detailed exceptions

[6r1d]

Today, sgull reported an error while trying to run the most basic documentation example while using a default config from the docs.

import json
from iroha2 import Client

cfg = json.loads(open("config.json").read())
cl = Client(cfg)

This is the error log, which, honestly, doesn't tell a lot to respond about:

Exception                                 Traceback (most recent call last)
Cell In[55], line 6
      4 cfg = json.loads(open("config.json").read())
      5 # cfg
----> 6 cl = Client(cfg)

File ~/.local/lib/python3.10/site-packages/iroha2/__init__.py:13, in Client.__init__(self, cfg, headers)
     11 def __init__(self, cfg, headers=None):
     12     if headers is None:
---> 13         self.cl = _Client(cfg)
     14     else:
     15         self.cl = _Client.with_headers(cfg, headers)

This error also repeats when he tries to run a test.py file.

We need to report if it's a malformed config that:

• Can't be parsed
• Misses some of the keys
• Doesn't allow Iroha 2 client to connect
• etc.

I'm certain there are several things I'm currently missing, and that doesn't allow to respond to the users. Let us discuss those and return to them later.
