[feature] add an option to output credentials instead of starting a shell

[T0MASD]

Please add an option to output the credentials for the export instead of starting the shell.
So it's possible to use it in automation like so:

export $(RH_AWS_SESSION_TIMEOUT=350 rh-aws-saml-login osd-staging-2 -o env)

in the future it could be extended to support things like

export $(RH_AWS_SESSION_TIMEOUT=350 rh-aws-saml-login osd-staging-2 -o json) 

etc.

May I ask what is your use case? Do you know that you can run any arbitrary command instead of opening a shell?

E.g.:

rh-aws-saml-login osd-staging-2 my-shell-script.sh

I run rh-aws-saml-login inside the container followed by
export $(osdctl account cli -i $ACCOUNT -o env -r $REGION -S) which assumes new account role, then I use rosa and aws cli, so having the current env populated instead of spawning new shell is highly desirable
