Running the command "rados df" on a cluster with long pool names or lots of data results in the stair stepping of the printed output. This results in data in a row not aligning with the column headings.

The requested change is to adjust the column widths prior to outputting the TextTable data.

Here is an example:

[root@overcloud-controller-0 ~]# rados mkpool areallyreallyverylonglongnameandthensome
successfully created pool areallyreallyverylonglongnameandthensome
[root@overcloud-controller-0 ~]# rados df
