Yong Tang 4e7e3919ce Restrict size to 2 fractional digits for docker images
This fix tries to address the issue raised in 26300. Previously
`docker images` will use `HumanSize()` to display the size which
has a fixed precision of 4 (thus 3 fractional digits). This
could be problematic in certain languages (e.g. , German, see
26300) as `.` may be interpreted as thousands-separator in number.

This fix use `CustomSize()` instead and limit the precision to 3
(thus 2 fractional digits).

This fix has been tested manually.

This fix fixes 26300.
