Enable IO Boost feature from Orka 1.5

In orka 1.5, a feature was released to improved disk I/O on VMs. We should enable it once the upgrade has happened.

Note that it doesn't work on High Sierra, so we need to update the autoscaler to be able to detect the OS before enabling the option on the VM configuration. This could simply be a check for 10.13 in the name, which is a relatively unique number.
