UI: Support enabling Elements of the Network Service Providers

ISSUE TYPE

• Improvement Request

In the UI, there is possibility to enable the Network Service Providers (e.g. VirtualRouter or VpcVirtualRouter) on the Guest Traffic - but that is not really possible until you enable the elements of those Network Service Providers (can be done in API, but not in UI).

Improve this to be able to enable Elements of each Network Service Provider - possibly do the needed API calls, but still with a single (existing) button, or possibly enable elements seprately (whatever is the easier way to do it) under each Network Service Provider

As this is an improvement request, it is better suited for version 4.20.0, as 4.18.2 is mainly for bug fixes and critical issues. I'll be moving the milestone to 4.20.0.
