docker build failed with error: The user requested boto3==1.5.3 redshift-connector 2.0.908 depends on boto3<2.0.0 and >=1.9.201

Docker build failing with error:

`sudo docker build -t amazon-redshift-utils .
`
```
ERROR: Cannot install -r /usr/src/app/requirements.txt (line 8) and boto3==1.5.3 because these package versions have conflicting dependencies.

The conflict is caused by:
The user requested boto3==1.5.3
redshift-connector 2.0.908 depends on boto3<2.0.0 and >=1.9.201

```

Start with requirements.txt, especially line 8, and reproduce the failure using the reported sudo docker build command. Review the boto3 and redshift-connector constraints in the error, then verify that the dependency resolution and Docker build complete successfully.
