Subject: [PATCH 05/11] Handle non existent ca-cert-config situation (#2073)
Currently if a cert file doesn't exist, cc_ca_certs module crashes
This fix makes it possible to handle it gracefully.
Also, out_lines variable may not be available if os.stat returns 0.
This issue is also taken care of.
Added tests for the same.
(cherry picked from commit 3634678465e7b8f8608bcb9a1f5773ae7837cbe9)
