AWS Lambda Python 3.9 support

Environment

AWS Lambda with Python 3.9 runtime. Sentry sdk version sentry-sdk==1.3.1

Steps to Reproduce

1. Change lambda runtime to Python 3.9
2. Raise exception

Expected Result

Error should appear in the sentry dashboard.

Actual Result

Nothing happens.

I found that in Python 3.9 runtime, AWS has changed bootstrap location, so return sys.modules["__main__"].bootstrap this is not working anymore. I fixed it with this sys.modules["__main__"].awslambdaricmain.bootstrap

I was able to trick sentry in finding it by doing this:

import sys
from sentry_sdk.integrations.aws_lambda import get_lambda_bootstrap

sys.modules['bootstrap'] = get_lambda_bootstrap().awslambdaricmain.bootstrap
sentry_sdk.init()

@jonapich this is very helpful. Just tested and it works like a charm. The transactions are coming back.
