[Kimchi-devel] [PATCH V6 3/3] add a method to check the i18n strings are obsolete

[shaohef at linux.vnet.ibm.com]

From: ShaoHe Feng <shaohef at linux.vnet.ibm.com>

There are some i18n strings are no longer in use in source code.
But they are still remain in i18n.py.

We should add a mechanism to check the obsolete i18n strings.
