Add utility to create/manage arn

[asanthan-amazon]

Describe the feature

In java sdk, we have class called Arn .

In rust sdk, we need something similar to create arn given serviceName and resourceName .

Use Case

We construct arn manually for several reasons.

1. When assuming role, we need to construct full iam role arn and give it as input to sts.
2. In policy variables especially ${ec2:SourceInstanceArn} , we need to construct full instance arn.

Proposed Solution

May be, a new crate like aws-sdk-arn ?
