Add tenant runtimeclass

[allanrogerr]

What does this do?

This provides the ability to set the runtimeClassName of a tenant in the UI. See minio/operator#1337 (comment)
Fixes: minio/operator#1337

How is it used?

The UI will invoke an endpoint using the free text string field"runtimeClassName": "<some runtime class name string>" from the Tenant creation screen under the section "Configuration"
e.g.
