Some resources, namely floating IPs, are limited based on those allocated, rather than in actual use. The "Allocated" string is present in the code but not used in the template. This effectively changes "Used X of Y" to "Allocated X of Y" for floating IPs. Change-Id: I7919b883a47d66b1e870862363d07e0f90bdbe7b Closes-Bug: #1708733
