163 yaml datasets (#284)

* 163 Initial commit showing that yaml dataset can be saved.

* 163 Refactor the yaml dataset endpoint and added pytests.

* 163 Exclude yaml dataset endpoint from open api spec.

Since this endpoint needs to access the request, the open api spec will not be generated correctly. To include this, extend open api: https://fastapi.tiangolo.com/advanced/extending-openapi/

* 163 Formatted with Black.

* 163 Fixes for mypy.

* 163 Added happy path test for patching yaml dataset.

* 163 respond with 415 if the wrong content type is specified a patch to the yaml dataset endpoint.

* 163 Respond with 400 when the dataset yaml cannot be loaded.

* 163 Added example of a YAML PATCH request for dataset. Named: Create/Update Postgres Dataset YAML

* 163 Added example of a YAML PATCH request for dataset. Named: Create/Update Postgres Dataset YAML

* 163 Test patching multiple datasets at a time.

* 163 Return specific yaml error in http response.

* 163 Ran make black.

* 163 Trying to get linter to pass.
