Allow teleport AWS access to work with aws tooling

[programmerq]

What

Currently, you must use tsh aws to access aws resources, but there are lots of usecases where it is important to be able to use unmodified applications and tools that are designed to work with aws directly.

How

I imagine it would be a similar workflow to accessing a db via database access or a kube cluster via kubernetes access. There would be a command that "logs in" to the aws console, and that writes out a config file or environment variables that other tools can take advantage of.

Why

To allow teleport users to take advantage of the vast existing ecosystem of tools that work with aws.

Workaround
