hypervisor: Add disk bandwidth and operations rate limiters
This is the disk counterpart of the what was introduced for the network as part of the previous commits in this series. The newly added fields are: * DiskRateLimiterBwMaxRate, defined in bits per second, which is used to control the network I/O bandwidth at the VM level. * DiskRateLimiterBwOneTimeBurst, also defined in bits per second, which is used to define an *initial* max rate, which doesn't replenish. * DiskRateLimiterOpsMaxRate, the operations per second equivalent of the DiskRateLimiterBwMaxRate. * DiskRateLimiterOpsOneTimeBurst, the operations per second equivalent of the DiskRateLimiterBwOneTimeBurst. For now those extra fields have only been added to the hypervisor's configuration and they'll be used in the coming patches of this very same series.
