Serverless using AWS profiles only half working

Problem

This is a Bug Report Description When using the `serverless deploy --aws-profile` or using the `EXPORT AWS_PROFILE=<profile>; serverless deploy` or the `AWS_PROFILE=<profile> serverless deploy` it only reads from the credentials file, but that should also be reading from the config file like the default `aws cli` tools does. For example I have the following two files [code block] If I run `serverless deploy --profile dev` it will fail with [code block] Then I tried `AWS_PROFILE=dev serverless deploy` and it failed with the above error And finally I ran `export AWS_PROFILE="dev" && export AWS_REGION=us-east-1` and then ran the `serverless deploy` and the same error occur. So reading more in depth the above small link and talking to people on Gitter I moved that dev profile to `~/.aws/config`, creating new keys since the previous used a cross account mfa role. Its my experience using Troposphere and tools that rely on AWS Profiles, they should be looking into all of them and if they have an mfa, request the code about it.
