### What changes were proposed in this pull request?
Use unit `bytes(IEC)`(`decbytes`, 1,024 bytes in a kibibyte ) for below 18 metrics(disk and memory related) instead of `bytes(SI)`(`bytes`, 1,000 bytes in a kilobyte).

### Why are the changes needed?
Some size related metrics use `bytes(IEC)` and some use `bytes(SI)`.

The main difference between bytes in the International System of Units (SI) and the International Electrotechnical Commission (IEC) is the number of bytes in a kilobyte:
SI: 1,000 bytes in a kilobyte
IEC: 1,024 bytes in a kibibyte

### Does this PR introduce _any_ user-facing change?
Yes, metrics unit changed.
### How was this patch tested?
Not needed, we already use `decbytes` in the dashboard json.
Closes#2896 from turboFei/unit_decbytes.
