ClientSession timeout AttributeError

[igorvoltaic]

Describe the bug

When you create a client with client.ClientSession(timeout=500) does not raise or warn that timeout must be implemented as ClientTimeout but fails when sending a get request
Code lets you implement a client as client.ClientSession(timeout='bad_arg')

To Reproduce

1. Implement a client with timeout of type int or float and send a get request

import asyncio
import aiohttp

async def main():
    # No issues creating a client session
    aiohttp_client = aiohttp.ClientSession(timeout=100)

    try:
        # Fails sending GET request
        await aiohttp_client.get("https://example.com", )
    finally:
        # Close client session
        await aiohttp_client.close()

asyncio.run(main())

2. Implement a session with timeout as str type

aiohttp_client = aiohttp.ClientSession(timeout='bad_arg')

Expected behavior

A ValueError has to be raised when using something other than ClientTimeout or None.
