Joel Thompson ee55e36af6 Check if there's a bound iam arn when renewing (#2819)
Previously, the renew method would ALWAYS check to ensure the
authenticated IAM principal ARN matched the bound ARN.  However, there
is a valid use case in which no bound_iam_principal_arn is specified and
all bindings are done through inferencing. When a role is configured
like this, clients won't be able to renew their token because of the
check.

This now checks to ensure that the bound_iam_principal_arn is not empty
before requriing that it match the originally authenticated client.

Fixes #2781
