core: update CGroupBlockIODeviceBandwidth to record both rbps and wbps
CGroupBlockIODeviceBandwith is used to keep track of IO bandwidth limits for legacy cgroup hierarchies. Unlike the unified hierarchy counterpart CGroupIODeviceLimit, a CGroupBlockIODeviceBandwiddth records either a read or write limit and has a couple issues. * There's no way to clear specific config entry. * When configs are cleared for an IO direction of a unit, the kernel settings aren't cleared accordingly creating discrepancies. This patch updates CGroupBlockIODeviceBandwidth so that it behaves similarly to CGroupIODeviceLimit - each entry records both rbps and wbps limits and is cleared if both are at default values after kernel settings are updated.
