TL;DR - Remove leading whitespace from accounting group names

We have the uid_table.txt and extattr_table.txt formatted for human
readability.  Example:

tiradani    group_cms

/cms/Role=production                    group_production

Previously, the line was split and the accounting group name was taken
as-is.  Now we strip leading and trailing whitespace from the accounting
group name.
