Quay Plugin:

Add the Quay plugin configuration to dynamic-plugins.yaml and ensure it's enabled by default.

Upon startup, the "Image Registry" tab must appear for the default "RHDH Local" entity in the catalog.

Justification: Demonstrates integration with external services and provides a practical example of extending the catalog's functionality.

Testing: This addition will require some prior thought and testing to ensure that if Quay were inaccessible for any reason the users experience would not be negatively impacted.

Quay.io Integration Defaults:

Add quay.uiUrl: https://quay.io to the default configuration.

Include proxy.endpoint entries for https://quay.io.

Add necessary img-src CSP (Content Security Policy) entries for quay.io.

Justification: Required for the Quay plugin functionality to work seamlessly out of the box.
