Fixes #146: cgroups_mem_max unit in config.proto

This commit fixes the incorrect cgroups_mem_max unit described in a config.proto comment.

We do not perform any calculations on this value and we don't specify the values unit (k/M/G) when writing to memory cgroup controller files, so the value is specified in bytes.
