Reusing code between resources

Hi, I'm from AWS IoT, we have a question/feature request.

Our handlers across different resources use the same code for exception translations and listing resource tags. These resources reside in the same GitHub repository, yet, since each resource has its own Maven project, we're unable to reuse that common code and haven't seen solutions in other repositories.

Specific examples from our AWS IoT repo (code is still in PRs):
1. Exception translation code - [link](https://github.com/aws-cloudformation/aws-cloudformation-resource-providers-iot/blob/09e62a47f99448c366eb7eaceb8c8ea76f8d6d36/aws-iot-securityprofile/src/main/java/com/amazonaws/iot/securityprofile/Translator.java#L295). We have this method in the Translator class for each resource.
1. `listTags` method (calls IoT::ListTagsForResource) - [link](https://github.com/aws-cloudformation/aws-cloudformation-resource-providers-iot/blob/09e62a47f99448c366eb7eaceb8c8ea76f8d6d36/aws-iot-securityprofile/src/main/java/com/amazonaws/iot/securityprofile/HandlerUtils.java#L46).

For both of these, we're able to reuse the code between handlers for the same resource, but we had to copy paste this piece of code for each resource.

Is there a solution available for our use case?
