[Multi-Tenant] Tenant selection dropdown in Admin UI pages

[mkurapov]

Context

Now that each of our resources is tenanted, whenever we are creating an asset, wallet address, or peer, they need to have a corresponding tenant selection drop-down.

If a tenant is an operator (determined by calling the query in #3124), we can populate the drop-down selection with all possible tenant ids.

If a tenant is not an operator, then the tenant id should automatically be set to the current active tenant id and should not be editable.

Todos

• Allow tenantId selection in create assets page
• Only show correct tenanted assets in create wallet address page
• Only show correct tenanted assets in create peer page

Prerequisites

• [Multi-Tenant] backend Admin Tenant API #3124
