aws lambda invoke does not complete

- [x] I've gone though the [User Guide](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-welcome.html) and the [API reference](https://docs.aws.amazon.com/cli/latest/reference/)
- [x] I've searched for [previous similar issues](https://github.com/aws/aws-cli/issues) and didn't find any solution

**Describe the bug**
`aws lambda invoke` command does not complete even though the lambda run has completed successfully

**SDK version number**
```shell
aws --version
aws-cli/2.1.6 Python/3.7.3 Linux/4.14.200-116.320.amzn1.x86_64 exe/x86_64.debian.9 prompt/off
```

**Platform/OS/Hardware/Device**
Inside debian container running on AWS t3.2xlarge/Amazon Linux

**To Reproduce (observed behavior)**
- Lambda with runtime more than 7 minutes
- `aws --debug lambda invoke --cli-read-timeout 0 --cli-connect-timeout 0 --function-name lambda_name --invocation-type RequestResponse output.log`

**Expected behavior**
cli to complete after lambda execution is done

**Logs/output**
- Command debug log
```
