core: introduce CGroupIOLimitType enums
Currently, there are two cgroup IO limits, bandwidth max for read and write, and they are hard-coded in various places. This is fine for two limits but IO is expected to grow more limits - low, high and max limits for bandwidth and IOPS - and hard-coding each limit won't make sense. This patch replaces hard-coded limits with an array indexed by CGroupIOLimitType and accompanying string and default value tables so that new limits can be added trivially.
