Org Control and Namespace Decommission

[ikethecoder]

This PR creates a V2 of the Directory API, which expands the set of operations available.

Particularly:

• Dataset management at Organization level
• Organization access management (RBAC and Namespace assignment)
• Namespace Activity searching by Organization (Namespace.Assign) and by Namespace (Namespace.View)
• Activity detail for Gateway Config changes and Namespace Delete
• Namespace Gateway summary
• Delete Product, Environment, Issuer, Documentation, Namespace
• Get Product, Environment, Issuer, Documentation by Namespace

Technical Changes:

• Enhanced the feed from CKAN to include "resources" and "contacts" to be stored in the "Dataset" table, so that they can be apart of the Dataset detail
• New V2 API with improved documentation, validation and examples
• Update build to support both V1 and V2 of the API
• Improved code coverage for backend services using Mock Service Worker (MSW)
• Switched Keycloak client from keycloak-admin to @keycloak/keycloak-admin-client
