Allow scheduler configuration with variable libraries

[Tom_Fosterbi]

The new scheduler is a great idea (Unlocking Flexibility in Fabric: Introducing Multiple Scheduler and CI/CD Support | Microsoft Fabric...)

However, the fact that we cannot control this using variable libraries means that if you have scheduled refreshed disabled in dev and test then after every prod deployment you have to renable the refresh.

There is also no way to turn off this new scheduler and go back to the old scheduler which did not move across environments.

Please either enable us to control the scheduler via depoyment pipelines ASAP or give us a tenant switch to disable this till this feature is supported.
