add support for aws profile

[Renkai]

This closes #806

[changhiskhan]

is this for recognizing the AWS_PROFILE envvar? if so, pretty sure that already works? How did you test before/after the fix?

[Renkai]

Yes, I have tested it locally. Before I add this tag the error information is IO("Generic S3 error: Profile support requires aws_profile feature").
With the flag it put data successfully.
BTW, aws_profile is a superset of [aws,aws-config,aws-types,aws-credential-types]

This looks fine. we'll figure out the windows CI issue later.
