Is HostSystem Compatible for a vCenter VM?

isHostCompatibleForVm.js

// VMware vRealize Orchestrator action sample
//
// Use VM-host compatibility checker, which is native to the vCenter plugin,
// to determine if a host is compatible with a given VM and resource pool
// 
// For vRO 7.0+/vCenter 6.0+
//
// Action Inputs:
// host - VC:HostSystem - vCenter host
// vm - VC:VirtualMachine - vCenter VM
// pool - VC:Resource Pool - vCenter resource pool
//
// Return type: boolean - is true if the host is compatible
