One use case for dependency substitution is to use a locally developed version of a module in place of one that is downloaded from an external repository.
This could be useful for testing a local, patched version of a dependency.

The module to be replaced can be declared with or without a version specified.

#### CRD Watcher

For watches against custom types (CRDs), we want to gracefully handle missing CRDs. Naively starting informers against the missing types would result in errors and blocking startup. Instead, we introduce a "CRD Watcher" component that watches the CRDs in the cluster to determine if they are available or not.
