(hotswap): allow support for arbitrary resource hotswapping

Please add your 👍 to this issue - that helps us prioritize!

### Description

Today, the set of resources that can be hotswapped (se the current list here: https://github.com/aws/aws-cdk/blob/master/packages/aws-cdk/README.md#hotswap-deployments-for-faster-development) is hard-coded by the code in the CDK CLI.

We should make this extensible, so that customers can add support for hotswapping new resources themselves, without having to wait for the CDK team to implement it.

### Use Case

There are many possible resources that can be hotswapped; right now, customers have no way of adding more, short of contributing changes to the `aws-cdk` package.

### Proposed Solution

We probably need to design some sort of plugin architecture that can load additional "hotswap plugins" when the CLI runs, similarly like we do for auth plugins.

I think it's fine to make this JavaScript/TypeScript only, since the CLI is written in that language. Making it JSII-enabled for multi-language support would most likely add a lot of complexity (and this task is already pretty tricky 😛).
