// Get the reservation policy IDs of all the reservations of a compute resource in a vRA IaaS instance

// For vRO/VRA 7.0+

// Action Inputs:
// host - vCAC:VCACHost - vRA IaaS Host
// computeResourceName - string - Compute resource name
// onlyEnabledReservations - boolean - Set to true to only return the reservation policies of enabled reservations

// Return type: Array/strings - reservation policy IDs
