Boto 1.36.0 release breaks sns_extended_client

[talsalmona]

I'm using sns_extended_client for a while now with no issues.
Upgrading to boto 1.36.0 breaks with the following message:

Error creating dataset: An error occurred (SignatureDoesNotMatch) when calling the PutObject operation: The request signature we calculated does not match the signature you provided. Check your key and signing method

Downgrading to 1.35.99 works as normal.

I think that this is related to a change in boto3 documented here: boto/boto3#4392

Proposed a solution in boto/boto3#4400

@talsalmona Looks like botocore 1.36.11 fixed it. Tested against region eu-central-1:

boto/botocore#3360 (from 1.36.11 on) together with boto/botocore#3351 (from 1.36.7 on) seem to be the PRs that fixes it for us.
