vcsim custom 'state' definition #1185

I'd like to define a custom state of a simulator instance (e.g. datacenters, networks, VMs, hosts) so that I don't have to remove the defaults and add my own at runtime. This would allow me to mimic what I have in my physical lab or even in production, and test different scenarios very quickly.

vcsim -dc 0 and your inventory is empty

Or vcsim -vm 0 if you want everything except VMs. Similar for the other types.
The flags are hooked up to the Model fields, we could have an option to specify in a file instead of the switches:

// Datacenter specifies the number of Datacenter entities to create
Datacenter int
// Portgroup specifies the number of DistributedVirtualPortgroup entities to create per Datacenter
Portgroup int
// Host specifies the number of standalone HostSystems entities to create per Datacenter
Host int `json:",omitempty"`
// Cluster specifies the number of ClusterComputeResource entities to create per Datacenter
Cluster int
// ClusterHost specifies the number of HostSystems entities to create within a Cluster
ClusterHost int `json:",omitempty"`
// Pool specifies the number of ResourcePool entities to create per Cluster
Pool int
// Datastore specifies the number of Datastore entities to create
// Each Datastore will have temporary local file storage and will be mounted
// on every HostSystem created by the ModelConfig
Datastore int
// Machine specifies the number of VirtualMachine entities to create per ResourcePool
Machine int
// Folder specifies the number of Datacenter to place within a Folder.
// This includes a folder for the Datacenter itself and its host, vm, network and datastore folders.
// All resources for the Datacenter are placed within these folders, rather than the top-level folders.
Folder int
// App specifies the number of VirtualApp to create per Cluster
App int
// Pod specifies the number of StoragePod to create per Cluster
Pod int

@jakerobinson do the flags above provide what you need?
