Inherit `role_session_name` from the profile specified by `source_profile`

### Describe the feature

To simplify AWS CLI profiles configuration it would be great to have an option to inherit `role_session_name` from the profile specified by `source_profile`.

### Use Case

We've got about 150-200 AWS CLI profiles configured to use `source_profile` to inherit credentials for assume role and each needs an individual `role_session_name` option to be set. It would drastically simplify things if `role_session_name` could be inherited from the profile supplied with `source_profile` parameter. Thanks.

### Proposed Solution

Inherit `role_session_name` from the profile specified by `source_profile`.
