    ms/memcg: rename memory.low_limit_in_bytes to memory.low
    
    This is how it called upstream (in the unified hierarchy). Another
    reason for rename is that memory.low is not actually a limit - it is a
    low wss estimate.
    
    Since memory.low was added not long before and it is only used by vcmmd
    and we are haven't released Beta yet, such a rename seems to be
    acceptable. In order not to break anything I'll make vcmmd work fine on
    both kernels with memory.low and ones with memory.low_limit_in_bytes.
