   I think I'm against this, but I can be argued otherwise.
   
   I'm a little skeptical that giving users the flexibility to specify the, effectively, globbing pattern is going to be super useful over just doing a containment search like the existing code does. Since APIs really shouldn't remove features, I kind of think we should wait for a user to request this before implementing it.
   
   However, the `_pattern` query param suffix indicates that the user should supply a _pattern_ for a URI, and the existing code just has them specifying a URI fragment, so that's not 100% ideal.
   
   But I'm also not a huge fan of putting SQL syntax into query parameters, or making this inconsistent with how [`dag_id_pattern` works](https://github.com/apache/airflow/blob/c954ce2126430ea3ebb56ac0a51a4762fb6d27c3/airflow/api_connexion/endpoints/dag_endpoint.py#L85). I would probably implement something more similar to globbing, and convert `*` at the beginning and/or end of the uri_pattern to `%` on the backend.
   
   I do think we should support exact matches though. What if we did something like how google works, and had more fuzzy matching on by default (eg: the current behavior), but allowed users to specify the URL in quotes for an exact match?
   
   Example:
   ```
   GET /api/v1/datasets?uri_pattern=s3  # Get all datasets that resolve to an s3 bucket (kinda sorta)
   
   GET /api/v1/datasets?uri_pattern=%22s3://...%22  # Get the dataset with URI exactly matching `s3://...`
   ```
