Quota bad unit

[JiffB]

Description of problem:
1)- Reading quota from a directory that was made with a base 10 number, ie.: 10000000000 (required, as a HDD's count is always in base 10 not base 2) displays base 2 results (GiB instead of GB).
Power of 2 make sens with memory, not HDD.

2)- Creating a quota with "10GB" creates in fact one of 10GiB (base 2).

This is a real concern as with a lot of users it fools the admin when he checks quotas - this is an even bigger problem when quotas have been set low and regularly grown to adjust to users' volume filling.

The exact command to reproduce the issue:
1)- gluster volume quota gv0 limit-usage /NIFF 10000000000
gluster volume quota gv0 list

2)- gluster volume quota gv0 limit-usage /NIFF 10GB
gluster volume quota gv0 list

The full output of the command that failed:
1)-

                  Path                   Hard-limit  Soft-limit      Used  Available  Soft-limit exceeded? Hard-limit exceeded?

                                           ^^^^^         ^^^^^             ^^^^^

2)-

                  Path                   Hard-limit  Soft-limit      Used  Available  Soft-limit exceeded? Hard-limit exceeded?

Expected results:
For 1 and 2 :

                  Path                   Hard-limit  Soft-limit      Used  Available  Soft-limit exceeded? Hard-limit exceeded?

/NIFF                                     10.0GB     80%(8.0GB)   0Bytes  10.0GB              No                   No

with a gluster input notation rectification from GB to GiB (or both, if people want to spend most of their time manipulating quotas filling a spreadsheet, it is their problem after all).

Irrelevant.

**- Is there any crash ? Provide the backtrace and coredump

No, just the use of an inappropriate unit.
