Unintended global logging configuration introduced in v1.10.0

[kiarina]

In version v1.10.0, a global logging configuration was introduced in the following file:

https://github.com/modelcontextprotocol/python-sdk/blob/main/src/mcp/client/session.py#L18

logging.basicConfig(level=logging.INFO)

As this is executed at the module level, it affects the global logging configuration of any application that imports this module. This can cause unexpected logging behavior and conflicts, especially when applications or other libraries have their own logging configurations.
