### Is there an existing issue for this?

- [X] I have searched the existing issues

### Feature description

Support for the Route53 Resolver service. Some common resources for the resolver service are the resolver endpoint, resolver rule, and resolver rule association.

### 🧑‍💻 Implementation

The service exists in the localstack/moto fork so my guess is the edge router just needs to load or connect to that backend.

### Anything else?
