// IntOrString is an alias for some returns from the Proxmox API where we've identified that some versions return a string, and others return an integer
// For example, LXC VMIDs were a string return in PVE 8.1.x, and are an integer in 8.2.x
// Since it can be either depending on the version of Proxmox queried, we're going to return the looser type. String in this case.
