AsyncBeacon: fix AttributeError by using aiohttp.ClientTimeout throughout

[lrusak]

Hello! I'm going to make a few pull request for some stuff I've been working on.

This fixes an issue I was having when using the async_beacon

What was wrong?

Traceback (most recent call last):

AttributeError: 'float' object has no attribute 'total'

How was it fixed?

by wrapping the request_timeout parameter with aiohttp.ClientTimeout

Todo:

• Clean up commit history
• Add entry to the release notes

More info

I'm able to trigger this issue with this example script

import asyncio

from web3.beacon import AsyncBeacon

import logging

import sys

async def main():

    beacon = AsyncBeacon("http://192.168.1.112:5052")

    beacon._request_session_manager.logger.setLevel(logging.DEBUG)

    handler = logging.StreamHandler(stream=sys.stdout)
    handler.setLevel(logging.DEBUG)

    beacon._request_session_manager.logger.addHandler(handler)

    for validator_id in range(1, 500, 1):
        validator = await beacon.get_validator(str(validator_id))

        print(f"{validator_id}: {validator}")

        await asyncio.sleep(0.5)

if __name__ == "__main__":

    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)

    loop.run_until_complete(main())

@lrusak Thanks for your contributions! This looks good to me but please add tests to check the sync/async request_timeout attribute is initialized with the ClientTimeout instance. I've added a newsfragment so we should be able to merge once the tests are ready!

[lrusak]

@reedsa I pushed a fixup to add tests for the timeout instance. I also reverted the change to the Beacon class because after inspection of web3/_utils/http_session_manager.py it looks like the request_timeout member should be float.

Let me know if that's acceptable and I can adjust the newsfragment also.

Looks great, thanks!
