Plugin doesn't support role assumption

[PingRIvis]

Any chance we can add role assumption into this plugin?

[PingRIvis]

It may actually support it but the documentation doesn't show how to use it... I am assuming role_arn like most plugins, but that isn't working in testing. Any chance you could provide a bit of help :-) Thanks so much! (testing with latest 1.0.3

@PingRIvis any luck with that? My logstash instance has access to cloudwatch via iam roles and it doesn't seem to work too :(
