[Multi-Tenant] Tenant List, Create and Edit Admin UI Pages

[njlie]

The Admin UI should allow the operator to view all tenants on their Rafiki instance, create tenants, and delete them.

• Add "Tenants" navigation menu item
• List all tenants in a table (similar to wallet assets, for example). Make sure if a non-operator is navigating to the table, only the tenant record for itself should be listed.
• Clicking into a tenant row should allow to edit the tenant details (
• If operator, a "Create tenant" button should be visible (similar to other pages)

For the creating and editing pages, the following should be configurable:

• API secret
• IDP consent screen URL
• IDP secret
• Email
• Public Name
