Add retry configuration for asyncio

[jhamon]

Problem

We want to use exponential backoff to retry failed requests made via PineconeAsyncio

Solution

• Add aiohttp-retry dependency without the asyncio extras group
• Implement a JitterRetry class to calculate backoff intervals
  • The off-the-shelf JitteryRetry class has some odd behavior so i wanted to implement my own. This helps keep the behavior close to what we're doing for urllib3.
  • Intervals are roughly 0.1, 0.2, 0.4, 0.8 seconds (plus small jitter factor)
• Manual testing with test server in scripts/test-server.py and scripts/test-async-retry.py

Type of Change

• New feature (non-breaking change which adds functionality)

Test Plan

Added some scripts for manual testing

Was there also a scripts/test-server.py file?

[jhamon]

It's already in. It got committed in a previous diff for urllib3 retries.

Thanks, was checking main not the branch 🤦‍♂️
