Clickhouse client ignoring `Username` & `Password` parameters.

[thuban-arrakis]

Steps to reproduce:

• Change cred envs to whatever you like, restart service - no difference

• Restrict default clickhouse user access from 0.0.0.0/0 to 127.0.0.0 network host.
  Check clickhouse logs:
  "Code: 516. DB::Exception: default: Authentication failed: password is incorrect, or there is no user with such name.
