aws configure list doesn't respect the --output switch

[michailw]

Describe the bug

While running the command aws configure list, the --output option is always ignored.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

Documented options should be respected, and output properly formatted:

--output (string)

       The formatting style for command output.

       o json

       o text

       o table

       o yaml

       o yaml-stream

       o off

Current Behavior

No matter what --output option I use, it always prints output in the following way:

NAME       : VALUE                    : TYPE             : LOCATION

Reproduction Steps

Run the following:

• aws configure list --output json
• aws configure list --output yaml

Hi, I'd like to work on this. I'll trace where configure list bypasses the output formatter and submit a fix.
