Support for AWS_SHARED_CREDENTIALS_FILE

[Julian]

It'd be great if boto supported the AWS_SHARED_CREDENTIALS_FILE environment variable that was introduced.

Seems like boto3 supports it just fine, but boto2 appears to not respect it (and just tries to directly look at ~/.aws/credentials regardless of whether it's set).

Joining that request..

Looks like this is not going to be implemented? 😢

[Julian]

@yermulnik that's generally an unhelpful thing to say on an open source project (and I say that even being the one to have filed the ticket here).

It's open source. If we're interested in the feature suggested here, the maintainers haven't objected, and it's not yet implemented, that's generally our sign a PR is welcome.

Looking at the number of open PRs it doesn't look like maintainers are accepting them...
So my quick workaround was this:
