[Service Fabric] Add managed cluster and node type commands

[a-santamaria]

Description

These cmdlets will support a New offering (resource type) - Service Fabric managed clusters for our customers. In this new model, Service Fabric resource provider (SFRP) manages the entire resource group for the essential components of the cluster, including VMSS, VNet/Load Balancer, and also storage account for diagnostics and bootstrap. In the previous model, SFRP manages a "cluster" resource that is mostly about the configurations about the cluster, the actual cluster runs on VMSS / VNet / etc that the customer needs to deploy in in parallel with the cluster resource and those are directly managed by the customer on their own.
