AWS component error in botocore

[pete1450]

Home Assistant release with the issue:

0.100.3

Last working Home Assistant release (if known):
Unknown

Operating environment (Hass.io/Docker/Windows/etc.):

venv on debian

Integration:

https://www.home-assistant.io/integrations/aws/

Description of problem:
I upgraded to the latest release and while I was doing so went to python 3.8. The aws component stopped working and I think I've traced it back to this pull in botocore: boto/botocore#1829

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

  credentials:
    - name: My AWS Account
      aws_access_key_id: mykey
      aws_secret_access_key: mysecretkey
  notify:
    # use the first credential defined in aws component by default
    - service: sns
      region_name: us-west-2
      name: sms

Traceback (if applicable):

Hey there @awarecan, @robbiet480, mind taking a look at this issue as its been labeled with a integration (aws) you are listed as a codeowner for? Thanks!

I have another project that started failing the same way.
Forcing these dependencies fixes the issue:

boto3==1.9.49
botocore==1.12.49

I guess something broke on a newer boto3 or botocore version.

The issue still persists and it fails to load the aws component.
HA Version 104.2

The issue is fixed in the 0.11.0 version of aiobotocore.
I manually went and changed the version of aiobotocore in the manifest.json of aws component to 0.11.0 and it resolved the issue.

Any idea when this will see a release? It's a real thorn in the side if you need to install awscli.
